This design transforms the normally 4 person game of KEEZ BORD into a three person game. It should fit the game perfectly, as I tried it out with the plastic variant of the game. If you thing it might not fit your style of board, print the non completed loop, as that is bendable and can thus be adjusted untill it fits
