Asymmetrical Spinner 1

While making penny spinners, my son and I discussed center of mass. He was curious why they would wobble so much if you took one penny out. I recalled that Fusion 360 has a feature to tell you the center of mass coordinates of your objects, which allows me to make spinners that are asymmetric. Basically, take any shape you want, compute the center of mass, and place the center of the bearing hole there. You have to be a bit more careful if the bearing hole cutout doesn't remove the same material all the way around (as in, there are open holes that reach to the bearing hole, or the spinner varies in thickness, etc). This spinner was my first asymmetric spinner, and I plan to make many more.
