The ball has a diameter of 80mm, a 9mm hole for suspension in the top and 10 x 5mm holes for LEDs in the bottom part.
It has a screw thread so that it can be screwed together and opened again at any time.
If you are interested, I can provide STL files without the holes for LEDS, as a closed ball with a thread.
The author marked this model as their own original creation.
