Twirly ear rings, shaped like the inside of an auger shell, with hooks.
Note the hooks are quite thin and come out of the printing process like wire, you may need to bend these to suit.
Tested with raw bronze and raw brass. Other materials not tested.
Note as this prints with hooks, and so is limited in the materials it can use. I have the same earrings that can be printed in plastic or silver with holes for BYO hooks.
