gyroscope inspired begleri

I saw something that reminded me of the giant gyroscopes that people used to pay for rides on at carnivals and park events. So I made a begleri. The outermost ring is 0.45in and the total should come out around 14.5g per bead. The rings are NOT designed to move (maybe a subsequent design). I feel like this is a design that would be incredibly difficult to machine, and is well suited for showcasing 3D printing ability. 

Note that this is a single bead, and for a set you need to order two.
