A Cube 2-Compound is a union of two cubes. Technically, what I've built is not a Cube 2-Compound, because I have just built the edges of the two cubes, but not the edges that result from intersecting the faces of the cubes, because I couldn't figure out a way to do it. Nonetheless, I think it's a nice construction
The two cubes are double-sized short. Their edges are yellow. First, I constructed one cube. I supported each face with four blue long bars and, because that isn't enough to make the cube stable, I supported it from the inside with red bars. I could not put more support on the faces because that would have made it impossible to add support for the second cube afterwards. Adding the second cube was comparatively easy. Some of its edges have to be supported by long bars (also blue).
