Be ware of a good first layer. If stuck together, try a little “massage” - if still problems, let me know. I´ll be happy to release a set with larger gap ( or a different size).
No supports needed - just a good first layer!
For those who do not have a PRUSA printer - I have uploaded “twoballs_easyprint.stl”.
If you do your own design, note how I made the invisible top surfaces.
The author marked this model as their own original creation.
