I've provided a couple versions of the ball - in 2 pieces and in 1 piece (not including the cap). I recommend printing it as 2 pieces. It's a lot smoother that way and the ball prints without supports. I've provided my PrusaSlicer 3MF files and MK3S+ GCODE for the 2 piece print at all 1X and 1.5X. I've provided the ball as 1 piece mostly in case someone wants to experiment with cutting it in a different place or you want to print the ball as 1 piece using a 3 color filament.
