Last year I experimented with creating casts using 123D Make, thereby turning a 3D model into whatever casted material one might like. I created the hollow casts using Make and, after assembling them as one would with any 123D Make creation, had a series of casting blocks that I filled with hot glue to create a large sculpture. The result was this:
This one used about 135 10" hot glue sticks. In this instructable I'll walk through making a much smaller one that probably uses something closer to 5 or 6 sticks.
