4 sizes of balls: 1", 1.5", 2", and 2.5". Split each sphere into its pieces in your slicer by ungrouping the bodies.
Each ball is made of 3 pieces, 2 half spheres and the threaded rod that connects them. They also have a hole in each half that allows for a rope or string to be put through them. This hole will have to be drilled out after printing. The holes in each sphere are 3/16" in diameter
No supports required for any of the pieces, the hole in each sphere is supported by a bridge at the base of the hole, which is why it will need to be drilled out afterward.
The author marked this model as their own original creation.
