Ultra Minimal Fidget Spinner

thingiverse

I created a minimalistic spinner using only the essentials. Cura estimates it will use 0.97 meters of filament and weigh just 2 grams with a 15% grid infill, printing in 20 minutes at 0.2mm resolution and 75mm/s speed. As expected from its design, the outer bearings can withstand minimal abuse before they pop out, but it still spins smoothly nonetheless. The spinner requires three standard skateboard bearings: 22mm OD, 8mm ID, and 7mm thick.
