Remixed from subthermal's cog: Cog

Features

The cog has an extended tooth for threading through the necklace chain. I recommend getting necklace chains from AliExpress if you don't mind a ~ 1 month wait. AliExpress

Printing

Didn't need to print with any raft as far as I remember, and you should get away with 10% infill.

If you liked the design, please upload your make, otherwise I'd be grateful if you left a comment! It'd be nice to know if this design came in handy for anyone
