Summary

Having food allergies, I always appreciate it when people include ingredients for the dishes they bring to a pot-luck. I was in search of sign ideas (other than the tented index card with hard to read writing that runs when someone inevitably spills something on it) when I walked past my phone charger and thought that something similar to that might make some great signs, and when done, could be repurposed as tablet & phone stands. If you tend to make the same few dishes for events, you can disassemble these for easy storage. If you regularly make your world famous pasta salad for the summer parties, and your also famous candied sweet potatoes, with those tiny marshmallows, for winter holiday parties, you could put one on side A and the other on side B, saving you some plywood. 
This works great for using up a variety of scrap 3mm plywood.
Holes for the stands are designed for 3mm plywood. You may need to unlock the ratio and increase/decrease their size if your material isn't 3mm thick.
