Christmas Fidget Spinner

Hi, I made this fidget spinner thing to get me through finals week. Works quite smoothly, you need 2 mr128zz bearings slotted on both sides. Place the end with the long square rod into one side of the sphere, then line the other side up and slot it in. This is designed with 0.15mm tolerances. You can add super glue to the square hole to keep it secure (optional).
