About this 3D model

The sphenoid hendecahedron is a space filling polyhedron. It is special in its low symmetry and creates visually pleasing patterns when rod like sub assemblies are formed. Considerable credits go to Guy Inchbald who published geometric data and description of these structures here http://www.steelpillow.com/polyhedra/five_sf/five.htm 2011 William Adams aka WilliamAAdams published a printable version of the more symmetric bisymmetric hendecahedron spacefiller http://www.thingiverse.com/thing:12800
