512 Tetrahedrons

Developed by Buckminster Fuller and popularized by Nassim Haramein, this cubic arrangement of 512 tetrahedrons (or tetrahedra) is also called the octet truss. Because of the tetrahedronal bracing throughout, it is an extremely strong structure for the amount of material used. It has numerous fascinating symmetries, and is considered by some to be part of the fundamental geometry of the universe. The strit diameter is just ove 1 mm, to print in raw brass and bronze, plastic, and possibly steel.
