Centrifugal fidget spinner (608 bearing)

Centrifugal fidget spinner

designed for 608 standard ball-bearing and 9mm ball-bearing-balls.

9mm balls are free to move in the arms of the spinner;
when rotating, they are pressed outside. Once it slows down, when spinning vertically, they drop down again and make nice, clickery sounds.
Spinning horizontally is silent - depending only on the bearing you use in the middle.

Assembly: fill one to three balls in each arm and push bearing in the middle. It's an easy fit, due to the open arms. Once I had my bearing fine, I secured it with a drop of super glue.

The taps I printed upside down with supports, to have the nicer topping surface on the outside.
