This is actually the third evolution of this fidget. With the first version of the fidget, the ball was stuck to the twisted polygon and could not move at all. To fix this problem I made V2, in which the ball could move freely. The only thing that was unsatisfactory was that the ball rotated less than 90 degrees. I changed this and changed the angles from 45 and -45 degrees to 90 and -90 degrees, ending up with Version 3, this file.
