The Platinum Cube is a Master version of Tony Fisher's Golden Cube in that it has shallower cuts which creates extra layers. It can also be viewed as a Master Skewb with the Golden Cube transformation applied to it.
I have designed it to be very accurate to Tony's original cube: one corner piece is perfectly equilateral, and some other pieces get placed in the center as well. I've also offset the puzzle not just in one direction, but in 2 different directions on different layers to greatly confuse the solver, similar to a Ghost Cube.
This puzzle is sold as a DIY kit from Shapeways. If you choose to order the DIY kit, keep in mind that you must assemble the puzzle yourself, and it is very difficult to do so. You will also need 8 M3 screws and 8 M3 washers. The stickers for the puzzle are available here: http://http://oliverstickers.com/stickers-for-shapeways-puzzles/ben-streeter
