The Rainbow 3x3x3 combines the cuts of of two puzzles: the 3x3x3 Rubik's Cube and the Rainbow Cube. The Rainbow Cube is a cuboctahedron with the cuts of a Dino Cube, but it does not have the same pieces because the face cuts are shallower.
If you order this model, you will get a DIY kit of the plastic parts needed to make this puzzle. You will need to supply your own screws (M3), stickers and springs for assembly.
You can also order an assembled copy of this puzzle from me directly, but this option is more expensive and it will take longer to get your puzzle.
Shapeways has recently changed their pricing making this model much more expensive. I've not yet had the time to optimize this model to be as cheap as posible. Please contact me at email@example.com if you are interested in obtaining this puzzle so we can discuss cheaper options.
