This is for m3 socket head screws if you need a small little bit to make the screw a bit wider in my case it was for a final project for a micro-controllers class to mount a LIDAR sensor. Go crazy with it I don't expect it to be really useful lol.
This takes any size M3 socket cap screw really I've not tested every one but I'm 99% sure it works with every M3 screw.
Recommended print settings are 3 wall 10% infill and a 5mm outer brim. It might possibly pull off on the bottom but it shouldn't be too much of a filament cost. Here is the recommended print orientation shown above.
