M3 Pin

thingiverse

This is a custom-sized M3 pin designed for situations where standard print terminals are loose but not threaded enough for a regular M3 screw. They rely solely on friction to hold in place, devoid of any threading. I printed this part using my Prusa MK3 with the "ultra detail" setting and was pleasantly surprised by their ability to grip securely. Given their small size, I'm confident that most printers can produce these pins with sufficient detail.
