For those that don't have the space or just need to raise up their board games a little higher to allow for beverages to be out of the way or cards or dice, etc... This is for you.

Each gameboard riser is 150mm X 150mm.This is designed to be modular, so you can use 3x2 (450mm x 300mm) pattern or 3x3 (450mm x 450mm) pattern but with fewer boards, you may need a few more legs for it to remain stable. The leveling feet shouldn't be necessary unless you're going for more height. If that's the case, print them at a slightly smaller tolerance(99 - 95%). The pegs are designed to fit in the recessed angle and glued. Once dried, you can then fit it into the protruding section of another riser board for a snug hold.

You can use some Neodymium magnets, 3x8's I believe(they may be a tight fit) in place of some of the pegs to create the attraction to each other. If you do, you can use 2 pairs on each outer edge with matching recessed and protruding section of each riser board. If you do, ENSURE you're using the correct magnetic pole for every single riser board, else you'll get issues when piecing them together.

No special printing requirements. You won't need supports on any of them. I do recommend printing 1 riser board first and then test fitting legs and pegs. They both should be snug fit.
