hyperbolic dakine toy

This is a really cool toy I saw on you-tube, and here's a video of what it can look like: https://1drv.ms/v/s!AqcF7c0kWqMOhNMiawVS30qDxyfEDA. When rotating too fast, the beads remain on the wheels; if you go too slow, you'll miss a lot of the action. To get the cool effect, you need to play with it and find the best rotational speed. I've updated the STLs for the bushings to fit the spindle better. I used superglue to bond the bushings in place, but the nut makes it easy to remove them. I haven't tried threading it using the inner series of slots or holes yet, so if you do try it, let me know how it works out for you. You'll need a few things to get started: one spindle, two wheels, two nuts, two bushings - inboard and outboard, and 50 beads. You can buy these at a hobby shop or print them yourself.
