Puzzle Cube Tray

Hi there -- just a simple pair of trays that fit a couple of the puzzle cubes that I've found here on thingiverse. There's one for a 3x3 block puzzle and one for a 4x4, though it really doesn't matter other than the smaller of the two has a 40 x 40mm, and the other 42 x 42mm.

It goes without saying that these are good for displaying on a shelf, but not so much in a drawer.
