This origami shape, designed by Shuzo Fujimoto, is a truncated octahedron, but with the square faces replaced by inverted pyramids. It is folded from a single sheet of paper. Due to the springiness of the Elephant Hide paper I used, the model would originally open up a little on the seam. Dry shaping (keeping it in fixed position using a rubber band for some time) forced the paper into place, and afterwards the model kept its shape well without any external support. Paper with low springiness and good memory would probably be easier to use for this model.
