Magnetic board game called Quarto.

Each player has 8 unique pieces and the goal is to connect four pieces with the same attribute (color, height, shape, and hollow/solid).

I printed these pieces in yellow and terracotta PETG with thirty-two 5x5x5 mm magnets. The magnet hole sizes are 4.98x4.98 mm to account for the settings of my printer, so test out a piece before printing all of them. If you don't care about the magnets, you can just ignore the holes and print normally and it will work just fine.
