Another Tri Spinner

This is another Tri Spinner with rounded edges for standard 608 skate bearings (8x22x7)

The holes have 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 bigger or smaller holes.

If you want nice rounded edges, you might need to enable support structures.
