This is a fully functional internal planetary gear spinner featuring a 12‑tooth sun gear, three 24‑tooth planet gears, and a custom 60‑tooth internal ring gear.
All parts were modeled in Onshape using real gear parameters (module 1.2 sun, module 1.25 planets and ring). The ring gear was created by subtracting a scaled 60‑tooth spur gear to form accurate internal teeth.
The assembly spins smoothly and works as both a mechanical demonstration and a fidget device.
Includes:
– Sun gear
– Three planet gears
– Internal ring gear
– Carrier
– Base
– Finisher
Recommended print settings:
– 0.2 mm layer height
– 3–4 perimeters
– 20–30% infill
Enjoy!
