M8 Hexnut-Flower Fidget Spinner

thingiverse

This Fidget Spinner is made for a standard 608 skate bearing (8x22x7) and five M8 Nuts (ISO 4032) The center hole has a diameter of 22.1mm, which is just the right size for my printing setup (0.4mm nozzle; ABS; 0.15 layer height). Scale the model up or down a tiny bit if you need a bigger or smaller center hole.
