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.
Printer : Print Rite DIY Rafts : No Supports : No Resolution : 0.1 - 0.35 Infill : 20 % Notes : Very easy to print.
I add 0.15 mm offset for holes for bearing and nuts.
If you get too big holes I would recommend increase extrusion multiplier for some %.
