Ball / sphere. Made of two parts and connected with a threaded insert. No support needed. No glue needed (but if you need strong connection you can use drop of glue). You can scale proportionally all parts to the size you need.

I used these print settings:

• layer height 0.2 mm
• nozzle diameter 0.6 mm
• no infill
• 2 walls
• 5 top layers
• 4 bottom layers

Attention! The ball has a displaced center of gravity. It is better to use for games where there is no need for accurate throws, rolling.
