Easy to print and assemble Great Ball
All parts are printed separately and placed together. The ring in the middle can be any colour and is just there to position the other parts. Everything just slots together.
Can be glued to stay together permanently, the red shoulders should be glued in as they do not stay in on their own. Alternatively you can scale up the internal ring in the z direction to decrease the tolerance and make a tighter fit. I used small amounts of blue tac to keep it together without being permanent.
100% size is 40mm
Top and bottom should be printed at low layer height, i used 0.12. other parts can be any layer height. No supports should be needed for any parts.
