About this 3D model

My first attempt at a spinner or really anything in Fusion 360. Most spinners are to big for 3-4 year old's so I wanted ones with closer outer weights. I like the size. Not to large and fits in your pocket well and I used hybrid ceramic 608's and spins forever. UPDATE: 6/17/17 I printed it and it works fine. Tapped the 608's in with a small mallet and the caps needed to be tapped to. They are a bit big and the offset from the spinner is bit but I like it. Lots of surface to balance on. I printed with PETG at 30% infill at .15 , I also printed the same in PLA. Picture shown is the PETG. Id like to see some makes :)
