Thanks, but I've already seen that one, I should rephrase my question. Is there anyone to make a 2x5x5 out of a 5x5x4 by gluing the top and bottom layers to the middle layers? It would be how you made the pillowed 3x5x5.
That is how Traiphum made this. I know because I've asked him and am in the middle of re-creating this puzzle for myself =) How you are asking it to be made is exactly how Traiphum made his. The idea has already been done before. Sorry.
