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.
