This interesting model by Shuzo Fujimoto represents a cube with a corner cut off. Depending on the proportions of the paper strip used, the cut surface is closer or further to the cut off vertex, resulting in a triangular or hexagonal shape. This particular model is folded from a 4:1 rectangle, resulting in a cut which goes exactly along three faces’ diagonals.
