One really cool thing about a fold-out cube is that you can print things on the faces without using supports and then fold up the cube to get an object with interesting protrusions all over. To print a closed cube with crazy sides would be really unreliable, but to print a flat one is easy. Here’s one crazily decorated hinge/snap cube net:

The Customizable Hinge/Snap Cube Net was made in OpenSCAD and then imported into Tinkercad, where we added all the crazy shapes. Here’s a public Tinkercad design you can modify to make your own Crazy Cube:
