Geometric Model by A. Harry Wheeler, One-Sided Polyhedron

notes: label: Description
content: The center of this cut and glued clear plastic model is a triangular hole. Both the top and the bottom of the hole have three trapezoids as sides. The long edges of the trapezoids form equilateral triangles at the top and the bottom, the short edges meet at the center to form a smaller equilateral triangle. Around the hole are three congruent irregular octahedra, each with four trapezoids as sides (two on the inside as just mentioned and two on the outside) and four triangles (two at each end). Each of these end triangles is coplanar with a trapezoid in an adjacent octahedron. Each of the octahedra is bisected by a trapezoid in the plane of the small equilateral triangle. A mark on the model reads: 685. Wheeler also assigned the model number M46.
