To make the Tetra-Dome 3 HZ model cut out along the perimeter edges, bend on a straight edge (example: counter top edge) at the interior lines, making a crease about 35 degrees. No bend is needed at the rectangle (Base Option) line.  Use tape to join adjacent edges to complete. For best results print on thick paper or card stock.
