If you wanna print it yourself, the model is here: https://www.printables.com/model/1348194-4n-threaded-flat-head-screws-and-nuts-10-32-equiva
Design to be a drop in replacement for 10-32 screws with a much, much higher pitch. These screws are extremely easy to print, is reliable enough that it can hold some weight.
If you wanna print this yourself, you need to make sure that the screw is sideways, so if it breaks it’s no on the layer lines.
Using them in my own prints which had metal screws and they are holding quiet well.
Thanks for sharing! Possible to do it with a torx head?
Anything with sharp angles will be likely strip it. Spanner Drive heads might do it, but it’s an uncommon type of screw bit.
why limit yourself to current bits? design and print your own bit head that’s strong for printed parts.
