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. (FreeCAD file on Printables) (lemmy.ml)

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.

Print them with an Allen key head, that's probably better than a Philips.

This. Or Robertson. Phillips is awful.

That's nuts.

Screw it. You get an upvote!

Do the layers seem to want to seperate when you twist with the orientation of the head slots? I feel like for two of the four arms, you're relying strictly on the layer adhesion.

My gut would tell me to rotate this by 45 degrees... But at the same time, if it ain't broke don't fix it.

I print on its side. It’s more likely to twist on itself than break the layers.

Useing a Hex, Robertson or Torx like the other commenters suggests will help with stripping.

Additional you could print the screwdriver or bit with the same material. If the screwdriver isn’t as strong as the screw they are less likely to strip. This screwdriver won’t last very long.

What I ended up going with is a combo of slot and spanner. Spanner for me to use a drill and a slot if I need a normal screw driver.
