Another Tri Spinner

thingiverse

This is another Tri Spinner with rounded edges for standard 608 skate bearings (8x22x7). The holes have a diameter of 22.1mm, which fits perfectly in my printing setup (0.4mm nozzle; ABS; 0.15 layer height). You can scale the model up or down slightly if you need bigger or smaller holes.
