The hinges are built to print together, fully assembled, using the "low" setting on a Replicator 2. What I'd really like is to have modular faces that you clip together after printing, since then I could make much larger polyhedra. Maybe another day... UPDATE: This is going to be entered in the Thingiverse "Math Manipulative Challenge", along with some more hinged polyhedral nets. http://makerhome.blogspot.com
