This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/bnocIDgyTGT
This replaces my previous model which was too fine for the MakerBot at my local library.
I'll print this next week and upload pictures of the completed image.
The idea here is to make embellishments for dungeon tiles, terrain and set pieces using a 3D printer and cheaper standard materials (Popsicle sticks, foam and cardboard) for the structures. Hopefully this method will allow for the creation of really great looking pieces with a minimum cost.
