The Rubik's cube
The Basic Stamp
Inside a Rubiks cube is a mechanism that has six stems coming from the centre. Each of these stems a centre piece is attached. These pieces can rotate with the stem being their axis of rotation. The entire piece is made from two parts, the internal part and the centre piece. Again these are in MLCAD format.
