Simple Fidget Spinner

Two 608 bearing are used for the spinner. You can use any model of 608 bearings (such as ZZ or RS, only difference is the seal). These bearing are cheap and easily accesable, plus if you have an old fidget spinner laying around you can use its bearings (Thats what i did :D). 

The fidget spinner perfectly fits through the palm and doesnt get stuck.
