I designed these in Tinkercad to fit the Munchkin theme. They help keep track of what level you are in the game. The instructions literally tell you to use whatever you want for this purpose. I don't think they planned on someone 3D printing a set of pieces, but here we are! Maybe one day I'll create pieces that interlock and are easily stack-able to distract the other players and ensure their swift defeat!

These print quite easily without any support. If you flip the model upside-down, and have your slicer skip printing the top layer (and set your infill to 0%), you can create a hollow model that is sturdy and uses less plastic. However, they don't stack as nicely when they aren't solid.
