Triangular polyhedral nets Free 3D print model

These are 2D nets made in Tinkercad that fold up to regular 3D polyhedra, specifically the tetrahedron, octahedron, and icosahedron which all have triangular faces. Printed with a Makerbot Replicator 2 on "Standard", which is .2mm layer height. The nets are made to have .2mm (one layer) base thickness plus another .2mm (another layer) for the faces themselves, which are inset just a bit from the base layer so that fold lines develop naturally. http://makerhome.blogspot.com
