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!

These models and openscad source file can also be downloaded from [https://github.com/jhpieper/sturdy-infinity-cube](https://github.com/jhpieper/sturdy-infinity-cube)

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.

Cube Sizes

It is best to not scale the model, as it messes with the spacing in the hinges.

Instead, check out these other models optimized for their size:

• 16: S
• 20: M -- try this first! This is the most common size.
• 24: L
• 30: XL
• 36: XXL
