Ring Stacking Toy

Wanted to model something in OnShape similar the baby toy called Rock-A-Stack. Basically a stacking toy, for rings of decreasing diameter. This is for my 16 month old to play with, and was another opportunity for me to learn more in OnShape.

I used 3 shells for the base, and created a hole from top to bottom of the shaft. The purpose was to give more strength to the shaft, and try to prevent the shaft from shearing off at the base layer. With those shells, and a hole going all the way to bottom of the part, I believe it will be a stronger shaft.
