Round Tuit Spinner

thingiverse

This is a simple spherical round-tuit and stand. As the sphere spins, you spell TUIT. The design uses a standard 608 ZZ (20x8x7) bearing that is pressed into a recess in the bottom of the sphere. The sphere is then mounted on the stand and can be spinned while holding the stand. The bearing is a tight fit both in the sphere and on the shaft of the stand.
