Fidget Spinner with Tri and Quad Versions

There are plenty of fidget spinners already available on Thingiverse, so why another? Two reasons: first, I enjoy designing things. Second, I wanted to try moving the mass of the weight bearings a bit farther from the center point than it is in most designs. It would seem that having the mass farther out would make it spin longer. My experiments seem to bear this out. I compared a Thingiverse design I printed with my own and got about 30 seconds longer out of mine. With a ceramic 608 bearing in the center, it will spin for about 2:45.

I also wanted to experiment with more weights. I designed the quad spinner to test whether more weight would allow for a longer spin. It seems this is not the case. With the same type of hybrid ceramic 608 bearing in each, the tri design spins about 20-30 seconds longer.
