Reinforced Double Walled Octahedron (Zen Magnets)

This video shows how to use Zen Magnets to reinforce the top and bottom faces of the double-walled octahedron (   • Double Walled Octahedron (Zen Magnets)  ). The resulting structure is robust and easy to build in large sizes.

The following table gives information necessary to build the reinforced double-walled octahedron in various sizes. The video shows how to build this shape for edge count 13 (second line in the table).
