Do you know the game Mafia? This game is similiar, the only difference ist the story and the roles. There are way more roles here. The maid can when the game leader shouts out who died last night, take the card from the dead player and turn around her card instead. So now she has a different role.
To print this you don't need a multicolor printer, because the color change is only on the first layer. So you just print the colors after each other and then you print the back in black last.
I designed this first in Inkscape and converted it then to OpenSCAD. I put all my files also into this gitlab repository: https://gitlab.com/ulPa/werewolf
