Fidget Spinner with M8 nuts

I was asked by my young neighbor to make a spinner.
I designed this one to be a little smaller and use M8 nuts to better fit in small hands.
Standard 608 series bearing is used (inner di 8 mm, outer di 22 mm, width 7mm).
Fell free to change something if required or add a customized text to the holding pieces I added also Fusion 360 files.

I have also a dangerous design:
