A cap for an M3 hex head screw to make a thumbwheel. It's 12 mm in diameter and 4 mm tall when finished.
Print on your printer of choice. This is a very simple part, and serves as a decent test/calibration item if you just want to make sure the printer runs. Note that if your printer makes internal holes a little undersized (many do), you may need to scale this part up by 1 or 2% to make it fit your hex bolt. If you scale it a little loose, some epoxy can fill the gap. Or you can print another one, since it should be fast.
