A hollowed out ring pendant with an intentionally bumpy spiral pattern on the outside.
Two 3x4mm holes that go straight through for a chain/line or other forms of mounting.
This version has a thinner wall, saving 0.5 cm3 of material.
I'm working on more models like this (single hole mounting, other patterns, even more optimised wallthickness).
