I converted a dead Ender 3 into a heat insert press tool
https://www.thingiverse.com/thing:6394749
I used as few non-Ender 3 parts/screws as possible.
Reused the X carriage as the Z carriage for the soldering iron.
I'm really happy with how it turned out.
STP file at the link in case you need to modify it for your particular Ender 3 parts.
Cool! Looks well designed parts.
Can you explain a bit more about what is it used for and how it does it?
Is it to seal packaging, join parts together, Does it automate the movement down to a set level and then pause for a duration and finally raise?
is it controlled manually?
It's for inserting brass threads into 3D printed parts squarely. More info on heated inserts here: https://www.cnckitchen.com/blog/threaded-inserts-for-3d-prints-cheap-vs-expensive
Thanks. Neat
