Helical Gear Wedding Ring

thingiverse

I wanted a wedding ring I could wear at work, not worried about losing it, or it getting wrecked , etc so I made a flat one 8mm X 1.25mm thick, but then got fancy, and made this one with helical gear teeth on it. 33 teeth, 16 Degree sweep, just because. With the gear teeth, I find myself moving it to my index finger and spinning it with my thumbnail like a tiny fidget spinner... This one is size 11, 20.95mm inside.
