It's true that you should not expect to save money in the short or long run with 3d printing as a hobby, but if it's your thing then it's nice to have a hobby that's occasionally useful. Also, autodesk fusion is free for consumer use.
I wouldn't say I've made back my investment on 3D printing in the past half a decade I've done it. But in terms of "prints for friends" like this one above I may be close. Plus there's just something nice about going "I need a measuring cup for dog food" and printing one to the exact serving size.
I just use PLA. PLA itself is good safe, but occasionally the additives aren't, so I don't use any for human related stuff. It's also worth considering that the layered approach can allow for bacterial growth, so unless you treat it (e.g. epoxy seal it), you'll need to wash it fairly frequently to curb buildup.
To be fair, that's the case with pretty much all plastics.
Tupperware shouldn't be used to reheat food in the microwave for the same reason, yet that's it's most common use generally.
Untreated PLA is more brittle than commercial food-safe plastics though, that is true.
Software is free if you aren't using it for commercial use. Fusion 360, onshape, etc. are all free for personal use. And that's assuming someone didn't make it already and share it free.
Filament costs $17 for 1kg of perfectly fine plastic. You'd probably use 100g at most for this, so $1.70.
A Bambu A1 mini is $200, and is a modern, high quality printer that would be fine for this project.
So you only need like a half dozen of these projects to come out ahead.
The recent 1.0 release is actually very good. It is probably better at this point than some of the entry level commercial options and most importantly compared to those is not intentionally hobbled in any way.
The time for everyone to stop parroting how "everyone knows" that FreeCAD is unusable is... now. You can go ahead and delete that one; it's time to learn a new soundbyte.
Come on. The 1.0 release is a huge milestone, but saying it's better than the entry level commercial options is just disingenuous.
I have actually switched over to it because I run a small 3D printing business as a side income, which isn't nearly profitable enough to afford an onshape license, and although Fusion360 has an affordable startup license it simply won't work on Linux and my hackintosh laptop isn't powerful enough for cad.
It is at a point where it is very usable if you are willing to invest the time needed to learn it, but the learning curve is much, much steeper than that of OnShape or Fusion360, especially if it is your first CAD program. There is also a huge lack of beginner tutorials for it, and the documentation is intended for advanced users, which complicates the learning curve even further, because Fusion360 and OnShape have a huge amount of beginner tutorials for them.
For a hobbyist that just wants to model a few things and not sell them I would always recommend OnShape or Fusion360 over FreeCAD, or even Tinkercad if said person just wants to model extremely simple things.
Yes. The 1.0 release was in November. That Ondsel fork in your video was based on, I believe, the 0.22 version.
The 1.0 release actually prompted Ondsel to shut down entirely, as they are now largely redundant and attempting to monetize a FOSS program was probably doomed from the start anyway...
Nah it's not you, FreeCAD is perfectly usable for something like the above referenced knob but even mid-size assemblies really have problems. I personally find the workflow to be bad and irritating beyond my ability to express in words and I can't imagine how frustrating it would be as a new user to work it out for yourself while at the same time getting used to thinking of objects as collections of operations. It's a great lightweight program for people who already know what they're doing and that value FOSS, though. 1.0 really fixed a ton of the issues, but it still has the "Blender UX" problem that seems to plague all big FOSS projects...
To be clear, I'm the last one to say one shouldn't invest in money saving innovation. But the breaking even should be number one priority. I, for instance have all kinds of energy savers in my house that have cost me several hundreds. They'll only be returned in a few years and I need to manage them properly.
One doesn't buy a 3D printer to make a knob. One is suddenly presented with a need for a knob (or a thingy, or a flangle, or a twizzlet...) and suddenly remembers, "hey - I have a 3D printer." Followed by "I wonder if there are any matching designs in one of the several massive free databases of models."
The type of person to do this most likely already has a 3d printer, and cad software is free for personal use. The electricity and filament cost for this part would be a few cents and it would take minutes to print on modern printers
Even if you didn't have a 3d printer it would be significantly cheaper to use a 3d printing service to order the part, than to buy OEM replacement knob
If you do not have a 3D printer and CAD software, you are 100% right.
If you already have those things like OP, then why not just design / print one? I am also a 3D printer / CAD person, and I love designing replacement parts that are wither too expensive, or often impossible to find. Mostly though, I design and print things that make my and my families lives easier / nicer / more convenient. And they are customized to the exact item and function, something that you would most likely never be able to get in a store or online.
I simply pulled the knob off in the store & shoved the rest of the stove up my butt, later at home I printed the missing knob. It's a simple life-hack, basically everyone is doing it.
I hate that as a society it is somehow ok to steal for your convenience. Its the same thing with lots of other things as well. Don't you just love it when you buy a product only to get home and find half of it was stolen?
A while back I would use those local secondhand auctions that mostly dealt in amazon returns. (As opposed to directly buying from amazon.)
I'm surprised how everything would be intact for a lot of items, but most commonly if I got bamboozled, it was something like, everything is fine except for missing a set of screws, or a single crucial knob or something.
People literally will just order the same thing again, pull the part they missed, and instantly return it. Which is especially scummy when it's no longer a secret these returns just get destroyed or incinerated for no reason.
It's just disgusting consumer-brain behavior. (Amazon, of course, being sheer evil, enjoys the market advantage of a "no questions" return policy.)
If it was a very specialty piece beyond a simple hardware store run, a lot of times I've been lucky enough to politely contact the manufacturer of a thing, sometimes I tell them I got it as a gift so they don't ask for a proof of purchase.
And they'll just send me the missing bit. Free. Super simple. The most I had to do was take a picture of the model tag.
The fact that this was too much for people to bother with grosses me out.
Not to say this behavior is okay, but there are some companies that also just exploit the alternative to high heaven, like the post shows. You can pay $20 for a 12 cent replacement part, or order one and return it. Some people will pay for the part, but significantly less will when it costs and arm and a leg for something so cheap.
I really appreciate that ikea instead has no questions asked small hardware replacement. Had a bed in my storage unit for years waiting for summers to kill the old landlord's "pets". Unfortunately in that time some important bolts rusted. Made me not need to throw the whole thing out
My oven is so old I came across an identical one in an e-waste pile behind a store. I stole the timer knob and mechanism so I don't need to keep using the broken one (manual only) anymore.
You're still putting too much work into this. Just heat up the metal shaft where the knob was with a torch and press any old hunk of thermo plastic onto it. Now you have janky done even more quick and cheap.
It's 100cm across and the branding has long since worn away. I think it used to say Panache on it at one point, but I can't find anything about that brand online. Following a trail of spares that look like the stuff on it, it was possibly made by Newhome.
I'd take a picture but I've not cleaned it in ages so it looks like something out of a crack den.
China mastered copying things well. A five pack of replacement knobs that actually match is $34 on Amazon. A crappy homemade knob for a $4000+ range is crazy.
China has also mastered modern slave labor. That someone makes thier own replacement instead of ordering some small uncomplicated part from across the globe isn't crazy, it's self-reliant and smart.
Oh I would go for the OEM part ten times out of ten, especially for such a nice appliance. Instead this person opted to make some plastic waste that will eventually be in the Ocean after we are all long dead.
Completely agree that Amazon garbage is terrible for humanity
I have a hunch that those knobs are just a thin sheet of metal wrapped around a piece of plastic, which would explain why one of the knobs broke off in the first place.
The knobs are "brushed stainless" plated plastic with plastic parts inside. It's possible Bosch is using higher quality materials, but this is the standard Bosch range knob that goes on all of their ranges, so I suspect it's made down to a price. They're injection molded parts that cost about a quarter a piece including parts and labor.
The important parts of the knob are all inside the range. But still can cost as little as about 10 bucks for an OEM part and 15 minutes of repair work if one of those should break.
Makes enough sense. My point was that either printing a replacement or getting the OEM part will use about the same amount of plastic, assuming the printing only takes one attempt.
It goes farther than that! The 34$ 5 pack is only that price because its already here in america to be shipped in a day or two. It came from china, where you can order the same thing for 1-5% of the price if you are willing to wait a month to receive it.
I was gonna bitch about it too but the cheaper Bosch ranges use the same knobs. It's an off the shelf part that Bosch is charging a ridiculous premium for.
I wish I had pockets big enough to replace the flimsy Bosch drawers in my fridge that start to shatter as soon as you pull just a tiny bit harder than normal.
Depends on the material. ABS would be a decent material for this application - as long as you have a decent enough setup to scrub / clean the air in the chamber / room.
PLA would have a hard time in that position, PETG might be OK, Nylon may creep after too many heat cycles. Depending on how hot those parts get this is.
50 degrees? How do your oven knobs even get that hot? Mine don't change temperature at all, always room temperature. If your oven knobs get recognizably warmer (yet to spend of 50°) something seems to be awfully wrong with your oven!
Not really. You can print it out of ABS easily enough if that's a concern, given that there is a good chance that is what the knob on any given residential range or oven is likely to have been made out of by the factory anyway.
As a matter of fact, since this is directly in my wheelhouse (not that wheelhouse, the other one) vis-a-vis both 3D printing and whitegoods, let's take a look.
Being in the unique position to be able to do so, I grabbed a knob off of a random smattering of ranges. Here's what I found from the ones that didn't require taking them apart further to find the markings or scraping at them with a knife or something (hey, there's the other wheelhouse):
Maytag (Whirlpool): Stamped "ABS" on the inside.
Bosch "Industrial Style" (similar to OP's): PBT
Whirlpool: PET
Verona: ABS
GE Base Line: ABS
PBT has a pretty similar melting point to ABS at ~235° C. With ABS it's complicated, but I print ABS at 260° C for what it's worth. PET is also typically given around 260-270. So these are all pretty similar to each other.
Depends on the type of filament used and temperatures that are actually present at the knob. I would say no since the temperature required to melt (or warp) the knob would have to be high enough to cause some pretty severe burns if you touched it with your hand. if the knobs on the oven/range are getting that hot, there is a lot more to worry about here than the knob melting.
From experience, we tend to use the same two burners, and one particular one, the most, by far. (Front left for us) After 15 years, the plastic on the underside of the original knob got worn and loose and almost broke. We rotated the burner knobs. The oven knob is doing the same thing, but it'll need to be replaced or repaired. Like someone else said, they aren't usually all metal construction, there's plastic on the inside.
If the knob on your stove breaks while it's still new enough to be sold on the floor of a Home Depot? Yeah, the theft wasn't by the guy who took the knob.
Where does it say it's new enough to be on the floor of Home Depot?
EDIT: Not sure why I'm getting downvoted with no replies, but ok. The title and image literally don't say anything about a knob breaking on a new stove. Just people getting mad about something that was completely made up. Every day Lemmy gets worse and worse (more like reddit); can't wait for the Lemmy exodus to take me to a new place.
-Massive donation and lobbying efforts to Republicans and Democrats (but they definitely go harder with Republicans, if you look at the numbers, and they've donated specifically to white supremacist candidates)
This reminds me of a story my mom told me over the holidays about buying a fancy sweater at Sears one fall. By mid winter the zipper had broken and she went back to Sears but they didn't have a replacement, and she didn't want a refund. They eventually agreed to have her take it to the tailor in the mall for them to replace it, and they would cover the receipt. She did and they did.
Blew my mind. If I honestly thought I could contact Maytag or Bosch and actually get someone on the phone to send me a replacement knob, I might bother. But I've moved past "try to contact the company with a reasonable concern" a long time ago. Which is what they hope for and why they make it time consuming and pointless. I'll take the path of least resistance.
If home Depot goes out of business because of all the stolen knobs, I'll cry myself into Rona every day (I mean that, I hate Rona and I use HD daily)
I like to keep the 3D printed look for spare parts, because its a good conversation starter and it often blows peoples minds if you tell them how cheap it was to produce. I was able to get at least 6 people into 3D printing now that way.
If people have little kids, or dogs that like to “counter surf,” guards are a pretty much a must (we just took the knobs completely off when our kids were little), acquaintances of ours lost their home to fire when the dog counter surfed and turned the gas stove on. I don’t remember what caught everything on fire that was on the stove, but they lost everything, and it killed the pets too.
Oftentimes for small elements like this you can just contact the company and they'll send you a knob or whatever.
(Probably won't be that lucky on repair parts though)
But I also enjoy the pride of seeing things I've repaired and longevitized with my own equipment. :)
Much more realistic that we'd intentionally spend $40 on a specialty roll of filament to have the right color and finish for that one specific print. See, I'm totally saving money! Right after I print, like, nine more of these!
I don't have a setup for ABS/ASA and been looking for affordable HT alternatives. Not sure how I haven't heard about this.
2.5x the price of PLA where i am, but not like I have better options on hand.
Yep, I usually print drafts in normal PLA and only the final part in the high temp stuff, but 2.5x is often still better than buying something if there's even a solution available. So, fine for me in edge cases.
A meme [/miːm/] is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme.
Feel free to keep reading on Wikipedia, or the dictionary, or wherever you may prefer.
You, my friend, are talking wholely from your ass. You are wrong, and also you're acting like a massive fuckwad. But you're probably 12 or 14 or something, so just read the definition of a meme before you spout off? This is a screenshit that is entertaining, and in no way is it a meme. If you can find it on "knowyourmeme" I'll be happy to eat a paper hat.
Learn not to be a dickwad unless you've done your homework.
oh man you think youre so smart dont you well let me tell you something buddy youre the one whos wrong and youre acting like a total FAKE news troll i mean come on youre trying to lecture them on what a meme is but youre the one whos clearly clueless and by the way i did the homework and guess what i found this exact thing on knowyourmeme so you can go ahead and eat that paper hat because you just got served and another thing whats with the age thing are you trying to be some kind of gatekeeper or something newsflash pal age has nothing to do with it but go ahead and keep on ranting but at the end of the day youre still wrong and thats the truth
no thanks i wont be using your elitist nonsense those little dots are made up and useless and a clear marker of government control because you know who used that stuff thats right hillary clinton and also adolf hitler both badguys

Still cheaper than getting a 3D printer and filament and stuff. And CAD/CAM software.

What food-safe printing materials do you use?
I just use PLA. PLA itself is good safe, but occasionally the additives aren't, so I don't use any for human related stuff. It's also worth considering that the layered approach can allow for bacterial growth, so unless you treat it (e.g. epoxy seal it), you'll need to wash it fairly frequently to curb buildup.
That frequent washing is what leaks out the nasty chemicals from the plastic fyi. Heat and mechanical stress are the main way plastics leach
To be fair, that's the case with pretty much all plastics.
Tupperware shouldn't be used to reheat food in the microwave for the same reason, yet that's it's most common use generally.

On software SIDE, kinda criminal not to mention FreeCAD, it's FOSS and runs on Linux, unlike the non-free freemium and paid alternatives
But it's got a long way to go before it's at usable as the others. Definitely not a good place to start learning cad.
No, it doesn't.

YOU WOULDN'T STEAL A BOSCH OVEN KNOB
Now you can
DON'T TELL ME WHAT I WOULDN'T STEAL
My oven is so old I came across an identical one in an e-waste pile behind a store. I stole the timer knob and mechanism so I don't need to keep using the broken one (manual only) anymore.
You didn't steal it, you 💫recycled💫.
*Reused, which is preferred to recycling even if the materials are 100% recyclable.
That's what I told to the store employee I encountered coming to work via the back door. He wasn't too happy but ultimately let me do it.
Imaging being mad someone is taking your trash.
Imagine getting mad someone is taking your employer's trash.
I'd eyeball the measurements in Blender and laugh at my crooked knob every time I use the stove.
I laugh at my crooked knob all the time.
That's at least better than his wife. She laughs and points.
You're still putting too much work into this. Just heat up the metal shaft where the knob was with a torch and press any old hunk of thermo plastic onto it. Now you have janky done even more quick and cheap.
What about the old vice grips that are now a permanent part of the stove trick?
Nothing is more permanent than a temporary fix.
Man, all the sinks I’ve seen over the years with vice grip knobs haha.
That's a humongous oven, must be a 10+ person household.
Or its the house people designated as the holiday house, maybe! Only actually used fully a few times a year.
That's my house. We have dual ovens and use them simultaneously several times a year, mostly holidays.
90cm.
We have one for our 4 adult, 2 kid household. Its amazing how often it's not big enough for all sorts of things.
I think 2 X 60cm ovens make more sense in hindsight and they also dont take as long to heat up
I ended up with 8 hobs, 2 ovens, a grill, and a drawer on mine. It was there when I moved in, and I kept it. Damn thing is built like a tank.
I've never had to use more than 2 of the hobs at once.
I use one of the ovens for storing rarely used pans and things.
That sounds like the 48" Miele. If so, hang on to it. That son of a bitch currently retails for $17,599.
No, that is not a typo.
Not as fancy as that unfortunately.
It's 100cm across and the branding has long since worn away. I think it used to say Panache on it at one point, but I can't find anything about that brand online. Following a trail of spares that look like the stuff on it, it was possibly made by Newhome.
I'd take a picture but I've not cleaned it in ages so it looks like something out of a crack den.
And yet it runs with gas, as if we're still cavemen cooking meat over open fires.
Its the cheapest ¯\_(ツ) _/¯

Oh I would go for the OEM part ten times out of ten, especially for such a nice appliance. Instead this person opted to make some plastic waste that will eventually be in the Ocean after we are all long dead.
Completely agree that Amazon garbage is terrible for humanity
I definitely agree that less plastic = better in general. But if you're going to 3d print stuff, at least this is functional.
And I'm not here to argue. God it is nice to have a civil discussions on social media.
Sorry if I came off as argumentative. That certainly wasn't my intent.
I was just trying to make the point that this person spent a lot of time and effort to do something subpar with plastic.
You didn't seem argumentative to me at all. I'm genuinely happy to disagree about something and:
-just have it be civil
-no one takes it personally
-we find things we can agree on
I have a hunch that those knobs are just a thin sheet of metal wrapped around a piece of plastic, which would explain why one of the knobs broke off in the first place.
I could be wrong, just a hunch.
The knobs are "brushed stainless" plated plastic with plastic parts inside. It's possible Bosch is using higher quality materials, but this is the standard Bosch range knob that goes on all of their ranges, so I suspect it's made down to a price. They're injection molded parts that cost about a quarter a piece including parts and labor.
The important parts of the knob are all inside the range. But still can cost as little as about 10 bucks for an OEM part and 15 minutes of repair work if one of those should break.
Makes enough sense. My point was that either printing a replacement or getting the OEM part will use about the same amount of plastic, assuming the printing only takes one attempt.
And Bosch makes and generally stands by their good products. Yeah they're a company, but they're not the worst!
Also, where did original knob go, I need to know.
Some things are better left unknown.
It goes farther than that! The 34$ 5 pack is only that price because its already here in america to be shipped in a day or two. It came from china, where you can order the same thing for 1-5% of the price if you are willing to wait a month to receive it.
I was gonna bitch about it too but the cheaper Bosch ranges use the same knobs. It's an off the shelf part that Bosch is charging a ridiculous premium for.
I wish I had pockets big enough to replace the flimsy Bosch drawers in my fridge that start to shatter as soon as you pull just a tiny bit harder than normal.
There are 3d models for some fridge drawers. I have a Frigidaire with similarly flimsy drawers and found a model for them.
How much did the printer and materials cost? Or the time to educate on cad and printing?
Just saying, it was likely far more money and time/effort than merely 12 cents.
If you didn't learn it only for this project, that cost is already sunk regardless.
Either way the post itself contains the answer for those who haven't already sunk that cost.
Also, aren't ovens hot? Won't a 3d printed part melt straight away, or is there some special material?
I don't think knobs get very hot
Well crap. Here I was hoping my knob would get hot.
Depends on the material. ABS would be a decent material for this application - as long as you have a decent enough setup to scrub / clean the air in the chamber / room.
PLA would have a hard time in that position, PETG might be OK, Nylon may creep after too many heat cycles. Depending on how hot those parts get this is.
There's a third, where the first person puts on thingiverse and we do it for fun without owning the actual unit
Wouldn't that be susceptible to melting due to oven temps? Or is that probably made from a higher temp filament?
What's the melting point of the regular filament? You're supposed to touch the oven knobs it so it's probably not much higher than 50 degrees.
50 degrees? How do your oven knobs even get that hot? Mine don't change temperature at all, always room temperature. If your oven knobs get recognizably warmer (yet to spend of 50°) something seems to be awfully wrong with your oven!
They should not be that warm but it's about the limit of what is comfortable to touch.
The comfortable temperature limit to touch is room temperature because anything higher indicates a broken oven which makes me highly uncomfortable.
50° K?
Hopefully if it's a decent oven there isn't that much heat on the outside. I guess if you just left the door open, it might eventually melt
Not really. You can print it out of ABS easily enough if that's a concern, given that there is a good chance that is what the knob on any given residential range or oven is likely to have been made out of by the factory anyway.
As a matter of fact, since this is directly in my wheelhouse (not that wheelhouse, the other one) vis-a-vis both 3D printing and whitegoods, let's take a look.
Being in the unique position to be able to do so, I grabbed a knob off of a random smattering of ranges. Here's what I found from the ones that didn't require taking them apart further to find the markings or scraping at them with a knife or something (hey, there's the other wheelhouse):
PBT has a pretty similar melting point to ABS at ~235° C. With ABS it's complicated, but I print ABS at 260° C for what it's worth. PET is also typically given around 260-270. So these are all pretty similar to each other.
TL;DR: You should be fine with ABS.
Oh sweet, knowing how to use a knife is right up my wheelhouse too!
Glass transition temp of PLA is around 55-60C - that’s when it starts to get malleable. I’d be pretty surprised if the oven knobs get that hot.
Depends on the type of filament used and temperatures that are actually present at the knob. I would say no since the temperature required to melt (or warp) the knob would have to be high enough to cause some pretty severe burns if you touched it with your hand. if the knobs on the oven/range are getting that hot, there is a lot more to worry about here than the knob melting.
But what the hell happened to the other knob? I've done a lot of stupid shit around the stove but I can't imagine what could happen to it.
Kids are a force
Wait you have kids and still sink money into crypto shillcoins? 😬
We wanted to fight corporate bailouts too, and it worked out well enough that we could afford to have kids.
From experience, we tend to use the same two burners, and one particular one, the most, by far. (Front left for us) After 15 years, the plastic on the underside of the original knob got worn and loose and almost broke. We rotated the burner knobs. The oven knob is doing the same thing, but it'll need to be replaced or repaired. Like someone else said, they aren't usually all metal construction, there's plastic on the inside.
Channel locks, adjustable wrench, or plyers are also acceptable. Plus then ya know damned well where they are.
This is why I always buy cheap vice grips whenever I see them in a box of tools at an estate sale or something.
"Oops, I broke a handle on (thing)."
Clamps vice grips on the bit left over
"Fixed it."
Right now both of the seats in my truck just have a vice grips for the reclining lever.
I had my shower knobs as vice grips for a long while
I just grab the serial number from a recently sold one and file a warranty claim on it.
That's fraud
Yeah? You should see the kind of crap my vendors are always trying to do to me. If anything the owe me big time anyhow.
If they're trying to do it to you, and you are aware of it, that means they're getting away with it.
Just thought I would point that out in case it wasn't obvious to you already.
Tell that to the judge.
They always wait until these people have stolen a bunch before they prosecute. It takes years to build a case.
Two wrongs don't make a right
Sure they do. It's wrong to take someone else's money. But if they take your money first, whoah, it just became OK! Same with hitting people.
What about a wrong to right the wrongs of capitalism?
I was reading some "I am a master shoplifter" threads on Reddit, and honestly I don't know why people don't steal more stuff.
I thought they banned the shoplifting subs. No?
They did, it was an AMA.
Just a thief?? That’s creative, solution seeking, and ecologically conscious problem solving right there
Those stopped existing when it became cheaper to just throw the whole thing out and buy a new one
Yes, he's just a thief. The ends don't justify the means. I can't believe that needs to even be said.
Sure, being a thief is bad, but one case of theft doesn't instantly make him a CEO.
Broken Window Theory is a load of bollocks: https://cssh.northeastern.edu/sccj/2019/05/21/researchers-debunk-broken-windows-theory-after-35-years/
If the knob on your stove breaks while it's still new enough to be sold on the floor of a Home Depot? Yeah, the theft wasn't by the guy who took the knob.
Where does it say it's new enough to be on the floor of Home Depot?
EDIT: Not sure why I'm getting downvoted with no replies, but ok. The title and image literally don't say anything about a knob breaking on a new stove. Just people getting mad about something that was completely made up. Every day Lemmy gets worse and worse (more like reddit); can't wait for the Lemmy exodus to take me to a new place.
Be the change you want to see, and leave.
Home Depot is not innocent.
-Anti-union
-Massive donation and lobbying efforts to Republicans and Democrats (but they definitely go harder with Republicans, if you look at the numbers, and they've donated specifically to white supremacist candidates)
-Underpaid employees
-Violated the National Labor Relations Act NLRA
Fuck 'em
Don't forget they donate to gay and trans reeducation camps right here in the US.
Yeah Lowe's sucks but I'll go there first every time.
Lol.
This reminds me of a story my mom told me over the holidays about buying a fancy sweater at Sears one fall. By mid winter the zipper had broken and she went back to Sears but they didn't have a replacement, and she didn't want a refund. They eventually agreed to have her take it to the tailor in the mall for them to replace it, and they would cover the receipt. She did and they did.
Blew my mind. If I honestly thought I could contact Maytag or Bosch and actually get someone on the phone to send me a replacement knob, I might bother. But I've moved past "try to contact the company with a reasonable concern" a long time ago. Which is what they hope for and why they make it time consuming and pointless. I'll take the path of least resistance.
If home Depot goes out of business because of all the stolen knobs, I'll cry myself into Rona every day (I mean that, I hate Rona and I use HD daily)
Hone depot hardly qualifies as "innocent"...
The workers that shit is going to roll down on are
How will it "roll down" on the workers?
Why do you think floor models sell for cheap?
Do you think the higher ups just shrug they're shoulders when the displays are missing parts?
All your doing is making some Home Depot worker's life worse.
Basically? Yes. Based on when I worked there for a stint.
The thief inspired me.
Or the longer version:
Simplest answer wins, and you could argue its not even stealing when its a display model.
Shoplifting is a noble crime.
Little sanding and silver Rub 'n Buff on that print will make it look a lot better and closer match to the rest.
Or even simply moving it to the middle of the set of three for less distraction.
I like to keep the 3D printed look for spare parts, because its a good conversation starter and it often blows peoples minds if you tell them how cheap it was to produce. I was able to get at least 6 people into 3D printing now that way.
And if you need guards for your knobs, I designed some after bumping mine and turning on the gas more than once.
https://www.printables.com/model/278668-stove-knob-guard
If people have little kids, or dogs that like to “counter surf,” guards are a pretty much a must (we just took the knobs completely off when our kids were little), acquaintances of ours lost their home to fire when the dog counter surfed and turned the gas stove on. I don’t remember what caught everything on fire that was on the stove, but they lost everything, and it killed the pets too.
Yeah, we had a different stove when our kids were small, and it had the knobs at the back of it.
I think some newer stoves will automatically shut off after a certain amount of time when the gas is on but no flame is detected.
Maybe I'm missing something obvious here, but how do you use the stove?
You push the knob in and turn it. The guard goes around the knob, but doesn't stop it from turning.
Ours are electric and can sit flush with the front after pressing them in. I meant soare parts in general 😄
Pro tip as a 3D printer owner/user though:
Oftentimes for small elements like this you can just contact the company and they'll send you a knob or whatever. (Probably won't be that lucky on repair parts though)
But I also enjoy the pride of seeing things I've repaired and longevitized with my own equipment. :)
I'd say more like 30 cents, but this one's clearly stolen - a real 3d printer owner would have had the right color filament on hand.
Much more realistic that we'd intentionally spend $40 on a specialty roll of filament to have the right color and finish for that one specific print. See, I'm totally saving money! Right after I print, like, nine more of these!
The two types of players
Edit: Here have a funny youtube video I reminded myself of https://youtu.be/CJpsL3XbD-M
Now THAT is a life hack.
But now it's the only one that doesn't look nicely polished, unlike the other knobs. 😁
If it was MY knob, it'd be polished on a daily basis.
Replace them all
Well done IF_TV!
Isn't that just selling?
Thats going to be a squidgy mess after a long cooking session. Hope he doesn't get plastic burns.
I think something might be wrong with your oven uh... my knobs don't get anywhere near the glass point of PLA when I'm cooking something.
I've always got a spool of high temperature PLA for that, good for up to 140°C.
I don't have a setup for ABS/ASA and been looking for affordable HT alternatives. Not sure how I haven't heard about this.
2.5x the price of PLA where i am, but not like I have better options on hand.
Yep, I usually print drafts in normal PLA and only the final part in the high temp stuff, but 2.5x is often still better than buying something if there's even a solution available. So, fine for me in edge cases.
They should buy some paint so it matches the other knobs.
Not a meme
Feels like fark.com all over again.
Holy shit, talk about blast from the past...
How many of you dipshits are there?
Learn what a meme is, you guys look dumb as hell spamming posts with this
A meme [/miːm/] is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme.
Feel free to keep reading on Wikipedia, or the dictionary, or wherever you may prefer.
You, my friend, are talking wholely from your ass. You are wrong, and also you're acting like a massive fuckwad. But you're probably 12 or 14 or something, so just read the definition of a meme before you spout off? This is a screenshit that is entertaining, and in no way is it a meme. If you can find it on "knowyourmeme" I'll be happy to eat a paper hat.
Learn not to be a dickwad unless you've done your homework.
oh man you think youre so smart dont you well let me tell you something buddy youre the one whos wrong and youre acting like a total FAKE news troll i mean come on youre trying to lecture them on what a meme is but youre the one whos clearly clueless and by the way i did the homework and guess what i found this exact thing on knowyourmeme so you can go ahead and eat that paper hat because you just got served and another thing whats with the age thing are you trying to be some kind of gatekeeper or something newsflash pal age has nothing to do with it but go ahead and keep on ranting but at the end of the day youre still wrong and thats the truth
That is the longest, dumbest sentence I've ever seen in my entire life.
ChadMc-3DayOldRemedialAccount. I hope you own a good helmet.
its obviously several sentences what are you illiterate and not that its any of your business but i have two REALLY cool helmets
Glad you are prepared!
See this thing --> .
This is how literate people delineate sentences.
I'm calling bullshit on your knowyourmeme photoshop, but it's funny to look at anyway.
no thanks i wont be using your elitist nonsense those little dots are made up and useless and a clear marker of government control because you know who used that stuff thats right hillary clinton and also adolf hitler both badguys
/uj thanks i was hoping you might giggle a bit about that but also what did you mean remedial account /j
Right back at ha, you clearly didn't absorb what you already quoted
Such confidence as you violently miss the mark
You should have tried that yourself
Yeah the other guy found t for you, eat up
The irony
Yikes. The other guy is a troll and admits it's Photoshop, but you didn't read that either.
Idiot. :)
Fucks given: 0, still not the guy who doesn't know what a meme is
