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

This plastic geometric model consists of four identical figures, each joined to the other three by a short edge. The middle is a large hole. Wheeler envisioned this model as four examples of his model 695 (MA*304723.413), arranged in alternating quadrants of a regular octahedron.
The Wheeler’s number for the model, 699, is written on one face. Wheeler classified the model as a one-sided polyhedron.
