An insert for Munchkin Deluxe with square box. I printed in some of the player colours, and with a room in the middle for dice and props. I own 2 Kill-O-Meters, so I made indents for them below the game board.

Print two of each model, and place them in opposite corners. NW and SE is one model, NE and SW is another.

Edit: I have now added a corner model for Double Dungeon cards. Print that instead of one NE-SW model.

Also,a box for the center spacer for more stability.
