The shape is two intersecting cubes. I first saw it in an M. C. Escher print many years ago. The model is folded from a single sheet of paper, a rectangle with a 2:1 ratio. Still, this is only a preliminary study. My goal is to fold it from a square and with a color change so that the two cubes are in contrasting colors. This will require six color change regions. Fortunately I have a method for this, similar to the way I affect the color change in my Stellated Octahedron.
