Infinity cube with strong hinges that won't break easily. This cube is designed with a lot of slack, so that it moves freely.

I designed this after having several fails with other models, where the hinges would break when trying to loosen them after printing. Hopefully, this design will print well for everyone!

This model is optimized for 0.2 layer height, including the first(!) layer. I use no brim and no supports, but hairspray to ensure good adhesion.

Post-Printing

The hinges should bent quite easily after printing, with the hinges on the front and back side being more tight due to the orientation. Just work the cube a few times and everything should be quite loose.
