A forum post on Board Game Geek point me to the idea of passing out a board game for Halloween that uses candies for pieces. But it involved 3 pieces being one way and 1 piece being another. I thought with 3D printing I could "carve" candy pumpkins quickly and easily. So I took some measurements and made an object to stamp faces into the pumpkin candies.
At this point the next step is making a tool that pressed into the candy would cut features out one at a time, but with Halloween fast approaching and other projects eating at my time it's not looking like that will happen. So I think this project is a bust for now. There's always next Halloween.
Really, I should start now on a Christmas project if I want to get the jump on that.
