I liked to make cube gears with rounded corners (not with sharp corners).
The design of whpthomas has only old pinpegs and is one type and does not provide a scad file. So I have taken the scad file by emmett and have made round corners.
Here you can have 3 different gear ratios of the cube.
At photo, the multicolor gearcube has unsymmetrical translated shape. stl not provided, uncomment in scad file if you need. To get the colors, I have put two 1.75-filaments in a 3mm extruder. Result are shades and layers.

- My original design of Globe Holder is for 45mm sidelength, it fits to whpthomas design.
- emmetts design is 50mm sidelength, In this reason I have scaled the holder to fit. STL file is one side, mirror in your slicer to get both sides.
- small gearcube is only downscaled version 50%. It does not work very good because of the extremely small pinpegs. My machine will not provide this precision. Also by scaling ve
