4x4x4 Eastsheen Cube

13.5 x 10.2 x 6.7 cm / 5.3 x 4 x 2.6 inch

This is almost certainly the first cuboid made with all different unit length sides. It's pretty enormous since I built it around an Eastsheen 4x4x4. The puzzle was transformed entirely by hand using high impact polystyrene plastic sheet and the pieces are hollow so it's very light weight. Movement is a little scrapey but I am pretty pleased with it's general quality. As stated my puzzle is fully functional. That means all rows and columns can be independently rotated. 
I have used standard Rubik's Cube style stickers with green opposite blue, yellow opposite white and red opposite orange.
The puzzle can change shape since it obeys the cuboid shape changing rule-
"A cuboid is capable of shape changing when ( 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.
