I created this interlocking grid system to play Qwirkle without worrying about the pieces getting knocked out of alignment at any point during the game. The grid fits on almost any 3D printer, prints with no supports, and you can print multiple (I recommend nine of them, laid out in a 3x3 grid) and use the interlocking dovetail design to keep them held snuggly to one another.
Tested and enjoyed! Have fun!
