Knob Cube
Click a thumbnail to see its larger version and description.
A 3x3x3 with one set of 4 cubies added to each side.

This concept is very similar to the Button Cube but it comes without the bandaging functionality. Compared with the button cube the added pieces are true cubies and are stickered. The face pieces of the 3x3x3 are completely covered in this puzzle and therefore it becomes difficult to see which piece has to go where.
The first design was made by Nikola Tutic. Masters (for subsequent casting) were printed too but the puzzle has never been completed until Karl-Heinz Diekmann presented his redesign.
