Fidget spinner
thingiverse
Made a fidget spinner with washers and bolts as weight instead of bearings. This way will save you the use of three bearings. The bolts are M4x8 mm, and the nut is a square M4. The washers are Ø18 mm. Bearing: ABEC-7 608 RS, all 608 bearings should fit. Print setup: Material: Innofill PLA silver (all "hard" materials will be fine). Heat nozzle: First layer; 205 C, afterwards 200 C. Heat bed: no setting. Nozzle size: 0.3 mm. Layer height: 0.15 mm. Support under each "washer space", if your printer is good at bridging it should be possible without support.
