I have designed a fidget spinner that takes 608 bearings for the outer 4 bearings and any bearing that is 22 mm in diameter for the centre. it needs a brim when printing or the outer prongs that hold the bearings will peel off the bed while it is printing. here is the link to the Tinker-Cad design: https://tinkercad.com/things/bv3X60FPlbr
We have a be nice policy.
Please be positive and constructive.
