This is an egg spinner that can be printed and used any time of the year to decorate eggs, but let's be honest, it's really for Easter.
3 Brass Rods (1.75", 3.25", 4.75")
Some drilling may be required
You may need to use a 1/8" drill bit to enlarge the holes on the rollers, gear, and handle so that a standard 1/8" brass rod can fit through the holes. May not be required depending on your printers tolerance.
For the base, I would suggest using a 9/64" drill bit so that the rod can spin freely.
Slide the brass rod through the rollers and then into the gears. The gears are "captured" in the recessed portion of the base so that the rod will not move.
