Fidget Infinity Cube

Yet Another Infinity Cube… but Fully Customisable

Yes — another fidget infinity cube 😄

But this one was fully designed from scratch in Fusion 360, with a focus on clean geometry, smooth hinges, and easy customization.

Infinity cubes are a classic fidget gadget: eight interlocking cubes that fold over themselves endlessly.

This version is designed to print in place, without supports, and to move freely straight off the build plate (after a bit of initial break-in).

The full design was created in Fusion 360, and the file is included so you can download it and customize your own version — change dimensions, add logos, engravings, or experiment with tolerances.

Print Settings

• Resolution: 0.2 mm
• Infill: 15%

Design features

• Print-in-place mechanism
• Optimized hinge tolerances
• Smooth folding motion
• Fully parametric Fusion 360 model

After printing, the hinges may need a bit of gentle movement to fully loosen up, especially the vertically printed ones.

This project is both a fun fidget toy and a great example of how to design functional, articulated parts in CAD.
