About this 3D model

The Fidgetspinners on the market are all really simillar so I made three Fidgetspinners inside of one Fidgetspinner. I will call it "Fid(Fidget)Get" You need 13 Bearings at all. 12 605RS/605ZZ Bearings and one 608RS/608ZZ Bearing. Search at you favourite Bearingshop for those Bearings. After assembling you have to use a hot knife or something else hot at flat to slightly melt the joint so the Fidgetspinner stay assembled and don't break apart while spinning. The Measurments for these Bearings are: 605: 5X14x5 608: 8x22x7
