Das Cube is Cubic version of
Das Twist. The mechanism makes sure that the stickered cubes always stay connected and together. The mechanism is based on the
Linked Cube concept by Evgeniy Gregoriev. The mechanism is upgraded in order not to have any overshoot when entering an illegal turn. This was achieved by giving each of the cubic edges a rim at different heights (
knucklehead style), that interfere with the sphere-part edges and corners, but not with the cubic corners or each other.

For future reference, I rendered images of Das Cube on July 10th, 2019, which I published on Shapeways early August. So I was surprised to see Walaber's 3x3x3 shapemod "
Odd Cube" on August 8th, which looks exactly the same, albeit without the Linked-Cube style mechanism. I must have been clairvoyantly inspired.
