This is a card holder for the board game 'The settlers of Catan'. It can hold 3 types of resource cards or 2 types of resource cards and the development cards. You will need to print two cardholders for holding all the different cards. I made it a stackable design for easy storage. The bottom is designed to have a slope going up to the front to prevent cards from falling out.
