Fidget Spinner Assembled

This is a sample fidget spinner model where I have considered real life dimensions of the piece itself. I divided this task into 4 major parts: 1) The plastic body of the fidget spinner(Green) 2) The 3 metallic pieces of radius 20 mm each 3) The central ball bearings(downloaded from GrabCAD) 4) Lastly, The finger caps at both ends of the ball bearings
