This model is completely redundant; the same shape can be made with 30 Sonobe units. It is made from 60 of a right triangle unit, and 30 of a connector unit, which is a square with one single crease. The end result is not really a great dodecahedron since the angles at the points of the sunken pyramids are 90 degrees.
