4x4x4 Master Cube / Rubik's Revenge

6.8 x 6.8 x 13.6cm / 2.7 x 2.7 x 5.4 inch

I made this puzzle from a 4x4x4 Master Cube / Rubik's Revenge many years ago. It was probably in the late nineties but I am not sure. Looking back through my old records I now remember that the new cubies were made from children's hollow building blocks. It's possible though that some were made with polystyrene plastic sheet since that was the technique I used in most of my later cuboids. Although quite large it is fairly light and the quality is good. I used standard Rubik's Cube style stickers for this puzzle.
The puzzle can change shape since it obeys the cuboid shape changing rule-
"A cuboid is capable of shape changing where ( two or more edge unit lengths are different and odd ) or ( two or more edge unit lengths are different and even ) excluding cuboids with a side of one."
In total I have made twelve fully functional cuboids. They are- 2x2x3 (micro), 2x2x4, 2x2x6, 2x2x7, 2x3x4, 3x3x4 (large), 3x3x4 (medium), 3x3x5, 3x4x4, 4x4x5, 4x4x6, 5x5x6
