Infinity Cube
thingiverse
I came across this on [reddit](https://www.reddit.com/r/woahdude/comments/azeztd/infinity_cube/) and quickly created a 3D model. If you want to modify the dimensions, there is an SCAD file available. This design has not been printed as a single piece yet, but it's likely that you will need some supports or get creative with orientation to achieve the desired result. For a truly mind-blowing experience, print six of the "puzzle piece" shapes and arrange them into the infinity cube. That's exactly what I did.
With this file you will be able to print Infinity Cube with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Infinity Cube.
