M10 Fidget spinner

I have been printing a few spinners for my son and daughter found here on thingiverse.
Now it was time to try designing one by myself.
It's using a standard 608 bearing and 3 M10 nuts.
It's a bit bigger than most spinners. Not for small hands.

I opened the bearing cleaned it with benzin. The result was astonishing.
This spinner kept on going for 3 minutes and 15 seconds :-0

I use the caps from this spinner by @Mr_MinerAl
