9/9/17: Added a new board (Board XL or Board XL with Fillets) with a bit more thickness to allow for 4 play pieces to be stored in each hollow section inside the board. Added a larger 3mm hole to allow for a larger machine screw to be used to secure the door.
Making this Tic Tac Toe board for my kids, printing it with multiple colors on the board and play pieces. I attached the color change files for the Prusa MK2S. There are also standard STL files of the play pieces along with the Fusion 360 files. One 2mm machine screw holds the door on and secures the pieces inside. All the pieces should print with no supports, on the board you might need supports depending on the bridging capabilities of the printer and filament..
