Hi! I currently, have 3 Pyraminxs, a Master Pyraminx, a Pyramorphix, and a Mastermorphix. I would like all of my cubes to be on display on one wall, but I cannot get another shelf. I have been getting a lot of cubes recently, and I have resorted to stacking them to conserve room. But the pyramid-shaped puzzles like the Pyraminxs have such a large base, cannot be stacked, and generally are just very inefficient for storing them. Any ideas? None of my plastic cube boxes will fit them.
