Rounded TPU Fidget cube

The original TPU fidget cube worked great, but I didn't like the sharp edges. So this remix has the edges of each of the cubes rounded so it feels better in the your hands. I have also posted a larger one with each cube at 20mm (based on another fidget cube with 20mm cubes (https://www.thingiverse.com/thing:1790624).
I've included an OpenSCAD file if you want to try different sized cubes and different rounding values. Note you will need to have the BOSLII library installed.
