Kingdom Death: Monster 1.5 Box Risers for Board

Corner and Side Risers for elevating the Showdown Board in the Kingdom Death: Monster 1.5 Box. Elevating the board keeps it from laying on top of the card dividers that stick above the tray that comes with the game.
I printed four Corner Risers and two Side Risers (for the long edge, to keep the board from flexing under its own weight).

UPDATE:
changes made to allow risers to work with my Kingdom Death: Monster 1.5 Rule Book support.
