About this 3D model
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: https://cults3d.com/en/game/circular-saw-blade-style-spinner-with-m8-nuts
