I finished my 3D Printable screw design! Excellent print ability, reliable for simple use, though the head is prone to strip... can't win them all.

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.
Ackschually, you don't need to print them entirely sideways for structural integrity. Printing at an angle should also work and you don't get so many artifacts from support material.
It's still a lot weaker than horizontal. Probably strong enough, but still significantly weaker. Personally i print horizontal without support, cutting bottom face through the head so it lies flat, though that won't work well if you need the head fully intact
