Soma Cube with holders

The Soma cube is a solid dissection puzzle invented by Danish polymath Piet Hein in 1933 during a lecture on quantum mechanics conducted by Werner Heisenberg. It consists of seven pieces composed of units cubes, which can be assembled into a solid 3x3 cube. This cube has edge length of 2.25'' when assembled (the unit cubes edge length is ¾‘’). The size is chosen so that this Soma cube piece also work for Bridges game (courtesy of Julia Robinson Mathematics Festival). Just make sure to print the guide pages on Letter-format paper and enjoy!

I also made three different holders for this Soma cube: a flat base, and two corner cubes with flared cylinderical bases. The two corner cube holders can be stacked on each other to enclose the puzzle, making for an interesting design.
