Next month I'm teaching a class on making game terrain at the local game shop and we are going to build this dice tower. Not exactly game terrain but a lot of the same meathods are used. Of course casting pieces for 12 people would be quite daunting and we want to cover other topics besides gluing bricks together. So I figure, what if I can design it to go together in 6 pieces instead? That was deffinately the way to go. The custom molds took every last drop of silicone that I had but totally worth it. As a side note, I discovered a piece of polycarbonate cleans beautifully and easily on my shaker table.
