This is the second version of my Rubik's Cube stand. I like it because it emphasizes the cube without drawing undue attention to the stand. Its spiral arms also hold the cube perfectly (much better than the last version).
Though it should work for any Rubik's Cube or cubish item, I created this mostly as an accessory to my fully functional and fully 3D printable Rubik's Cube. It's linked below if you want to check it out.
