This allows members full access to all of my uploaded models, and I'll send any interested viewers a pdf file with pictures of more than 100 of my 3D models, which are available in nylon, colored prints, and metals. They are largely mathematical , ranging from colored models of nested Platonic solids, to models of the diamond crystal the gyroid ( a molecule found in iridescent butterfly wings), Fibonnaci flowers and spheres, Buckminster fuller domes, trusses, and symmetry spheres, projections into 3D of 4D solids, and more.
