Classroom Spinner
thingiverse
Designed this for my kindergarden class. I left the magnet bolt solid to allow you to customize for your magnet. Just drop stl file in tinker cad and make hole with the dimensions of your magnet. (get a strong magnet) Note: I printed 15% infill with "lines" setting. My suggestion is you do the same, different settings might screw with the balance, and that would be bad for a toy designed to be perfectly balanced :(
