Planetary Gear Spinner | Print-in-Place
Description
Probably the smoothest gear spinner I’ve made so far 😅
This is a fully print-in-place planetary spinner with 8 moving planet gears and herringbone teeth, so it feels super smooth and satisfying when spinning it. The whole thing prints assembled — no supports, no screws, no glue.
The outer ring has a nice grip to it, and the center finger hold is really comfortable once it gets spinning.
I spent way too much time tuning the clearances and chamfers so the gears wouldn’t fuse together while still keeping that dense mechanical feel 🔥
