The board game Pandemic comes with pieces in little baggies, but the bags fall apart fast. I designed these holders for all the wood and plastic pieces so that setting up and putting away the game is fast and easy.
You'll need to 3D print the bottoms and two of the tops. The tolerance is tight on the hinge, so you may need to sand or xacto knife the sides of the hinges so that the parts will fit together.
You can straighten a paperclip and shove it through the hinge. Any small wire will work, and it doesn't need to go all the way through; just at each end.
