10 mm nut Figdet Spinner

This is a Fidget Spinner, that i made really quick.
It is configured to use (Inner diameter, outer diameter, height) 8x22x7 mm ball bearings. I have made caps to press in to the bearing, to minimize drag when spinning.
And it uses 10 mm nuts as weights in the arms.

You can use ordinary ball bearings, or ceramic ball bearings. The ceramic ones has a lot less drag so they spin longer, but they are more loose.
