Description
A compact, print-in-place fidget spinner with a fully working planetary gear system. It features six 12-tooth planet gears rotating around a central 24-tooth sun gear, all within a 55 mm body.
No assembly required — just break the parts free after printing. Make sure your printer is well dialed in for best results.
Includes four different outer ring styles: smooth, knurled, spikes, or dimples.
Prints in about 1.5 hours using only 15 grams of filament. Seam position is set to random to avoid marks on the gear teeth.
