Cube and ball fidget spinner keychain - Print in place

This cubic keyring and ball spinner is printed in place with supports. 

The ball rotates freely in the cube with a tolerance of 0.4 mm.

If you look at the print file provided, you will see that I printed the cube with a 50% infill and the ball with a 25% infill. This setting is not mandatory; you can choose to print the whole thing with the same infill. 

As for the supports, I did not choose the “supports everywhere” option, but used the “supports only for support generators” option so as not to put them in inaccessible areas.

Dimensions of approximately 28 mm x 41 mm
