For fun! Note: if you don't want to use the same bearings as me, add a negative to the Cylinder Base that is equal to the outside dimension of your bearing. To the mushroom you need to add a part that is equal to the inside dimension of your bearing. If you choose to use the same bearings as me, you will get much longer rotations. If somehow the correct bearing doesn't fit, scale the products. 

Use matte colors. Shrinking can be different. If you use same ball bearing like mine, you will have arround 2 minutes spinning. You can find on my page.
