Simple to print table tennis balls case with screwable lid.
Holds 3 balls.
This is second version with easier to print thread, no supports needed anywhere.

The case is very sturdy for me, printed easily.
The lid fits perfectly for me (Bambu printer), but if you find it too small, increase the size to 101% and should work fine. Doesn't take long to print the lid.
Also there is a simple lid and a lid with Butterfly logo.

Enjoy and please share the results!
