This is mainly because consumer 3d printer have been developped by 3d printing enthusiast first and not a company, Prusa which was leader for some time used a lot of open sources project to build their printers. As it's getting mainstream as time goes by more and more companies shows up with closed sources project sadly.

AI aside, I disagree with you. I've seen in past people with modelling knowledge posting stuff (openscad, stl...) without having a 3d printer and to me, that wasn't an issue as long as they specify it in description (most of time they did), they would also take advice IF they were printing issues and would fix it. So yes, I could lost a bit of time and filament but nothing compares to the time those people invested to share/give away their work to the world while they were not even in a position to print their own stuff.

Blaming site is an easy solution, but let's be honest. If they were to verify everything uploaded+description, we would end up with ads everywhere, click baits making site unusable or paid subscription...

Let's not forget that 3d printing/printer has grown thanks to people sharing their knowledge and failures. If I have to fail a print because I'm lacking on modeling and therefore depends on others people work, that's not a problem, I'm just there doing my part and giving feedback so we can build something better all together.

There is also "consent o matic", banner does appear but go away in less than a second and auto decline as possible. Does not work on 100% of website but still does a good job.

You can search for "9 2009" to help finding it. Not on first page but does appear (check pm)

Meanwhile bambulab do not want to recognize an issue which could lead to a fire...

Also transmission which is also open source

Not exactly what you asked but just in case, you can free some robot from cloud using valetudo List of supported device can be found here

Emby was but not anymore (for a few years). Only jellyfin is open source

In MAS we trust! :D

I don't print asa so won't be able to tell you which printer is good but don't forget that asa release fume and substances dangerous for health, better have a place design for it with exhaust and all the necessaries.

I don't use matrix so cannot answer with precision but you can create an automation and use vacuum state as trigger (ex: from cleaning to dock) and use notify platform to send to matrix whatever message you want

My guess is that your issue is from torrentio, I don't use it but heard a lot recently about instability. You could try comet instead of others.

(not OP) Have seen an article in a french magazine called "60 millions de consommateurs" it is a well known magazine from "national institute of consumers" and they provide neutral information for consumers and very often tackle corporate. They also help people with specific problems by using there legal departments and others technical departments.

extract from article: (auto translated so could have some errors, feel free to ask if necessary)

"How we did it

• Ten letters from readers sent in 2025 to the editorial staff of "60" were selected. Messages asking questions, sometimes thorny, on the main consumer topics: banking, housing, health, guarantees, and even transportation.

• These questions were submitted in August to three free artificial intelligences: ChatGPT-5 (OpenAI), Gemini 2.5 Flash (Google), and Le Chat (Mistral AI).

• Each response was dissected by the legal or technical department of the National Consumer Institute. Is the advice given accurate, incomplete, or far-fetched? The most convincing AI was distinguished, unless all failed to answer correctly."

One example of the letters: (same as above, auto translated, added some context for ease of understanding)

" A questionable rent increase

<< We have been renting since August 2013 and we have just received a registered letter announcing a rent increase. However, we have no information about the revaluation index in this letter, nor in the lease. Furthermore, I have just discovered that a landlord does not have the right to increase the rent without having provided an energy performance diagnosis (DPE). What can I do?>>>

AI responses: our analysis

ChatGPT and Le Chat point out that the Climate and Resilience Act of August 22, 2021, prohibits rent increases for F or G housing [these letters indicate energy performance diagnosis], which is an energy sieve. Le Chat rightly advises asking the landlord for the DPE and contesting the increase if it displays F or G. If the dispute persists, he recommends consulting a lawyer or a tenant defense association. He could also have cited the justice conciliator!

Chat gpt and Gemini are more vague or even incomprehensible. Gemini states that the "landlord has the right to increase the rent even without an DPE, unless the energy class of the housing is F or G." An energy class given without an DPE, really?

Winner= Le chat"

"Verdict

With three correct answers each, ChatGPT and Le Chat have a narrow lead over Gemini. This doesn't stop them from making mistakes, or even inventing convenient legal passages to support their arguments. Surprisingly, the upgrade from version 40 mini to version 5 in early August caused ChatGPT to lose its advantage in two cases! Disappointing for an AI supposed to behave like "a PhD-level expert," according to Sam Altman, head of OpenAI, its publisher. As it stands, it's difficult to recommend one AI over another. To increase the quality of the answer obtained, cross-reference it with those provided by other AIs. The safest course of action is to make an appointment with a real lawyer. To obtain a free consultation with a professional, contact a consumer association or one of the approximately 3,000 legal access points spread throughout the country"

It's not a simple bridge as you have a square in the middle, walls are printed first so it messes up the layer. Just add support either to the whole model or just beneath the square. Alternatively, add one layer at bottom of the square so it will do a simple bridge and cut it off after. Edit: just had a look at the preview and yeah the curves wall are not best for bridge but don't use creality slicer so can't help

Might not help you a lot to decide but something to take into consideration... While bambulab printer is close to plug and play (can't talk for there others you mentioned), because of closed source, finding fixes to some issues can be sometimes problematic. You can find documentation but way less than other printers as they hide a lot of knowledge...

Your friend may not have issues with it yet but it if you go on bambu lab discord server, you will see that many people are having issues. What I mean is all printers can have a lot of different issues so don't believe that if you take a p1s, you won't have any problems. 1 person may not have much issues for a long time but meanwhile 10 people will struggle.

By the way, some may think "another bambulab hater blablabla" while reading my comment but I have 3 printers and one of them is an A1, so no, I'm not a hater, overall I like it but that will be my last bambulab printer for sure.
