Fidget Cube (with rounded edges now, remix)

This is a remix of the best printing (and fun) "Fidget Cube" that I've found. Credit to Kobayashi!

I tend to print it scaled down 20% (16mm instead of 20mm for the smallest dimension is the smallest I'd go) or so. It prints well larger or smaller than the default size.

I was able to print this without support. You can try it with or without support.

I added fillets to every sharp edge so it feels better in your hand while "fidgeting". 3d printers are so good at creating sharp edges, that it tends to wear on your hands after a while. This one feels better.
