Download Free 3D Model Fidget Spinner – 3 Curved Wings 3D Print Model

Summary
Simple design requiring a 608 bearing and 2 end caps. I use PLA and have calibrated my printer so that the hole is a press-fit with the bearing.
How I Designed This
Fusion 360 is really excellent for design these days. It is free for hobbyists as well. Takes a while to learn, but they’ve added integration with 3d-printers, so you can send your design directly to your software, such as Repetier Host. It also exports to stl (which is how I get the files for thingiverse). My 10-year-old can now design his own spinners.
