I, Jerm, present to the cubing community a puzzle that will prove to be among the most difficult of cuboids. With different, but even layers, the 4x6x8 shapeshifts on all 90 degree turns. This makes the puzzles solve even more challenging, forcing the solver to go through multiple stages just to get it solved. Since it is an even layered puzzle, parity situations which are not found on odd layered puzzles are present.
You can buy stickers for this puzzle by request at Oliver Nagy's shop: http://speedcubing.hu/webshop/. There is room for a spring set in this puzzle. 6 m3 screws, and 6 springs are needed.
I must warn anyone who buys this puzzle, that it is indeed, very difficult to assemble. it took me a couple hours to do so. The last 3-4 pieces are the most difficult to put in. they need to be put in simultaneously with the last core stem, and then the screw needs to be tightened.
I highly recommend that you buy the POLISHED version, which will make it 10 times easier to assemble. For an extended period of time I will offer dying, assembling, stickering, and breaking in of the pieces for $300 USD. Contact me through shapeways, and we can work things out together if you want that done. :)
