Quarto game with box, pocket size, customizable (FreeCAD)

Do you want to take your exiting strategic Quarto game with you to your friend - but don't want to carry the big box of the original game with you? This version solves the problem: No big box, no separate big board - All pieces fit into a small box which is also used as board during the game.
With a diameter of 12mm for the pieces - the box is only 97x49x16mm.

I also added the FreeCAD design file which allows you to easily customize the pieces and the box. If you change the size of the pieces in the "sizes"-spreadsheet, the box adapts automatically to the new size - so you don't need to adapt it, The FreeCAD-design file is inside of the Quarto&Box-FreeCAD.3mf. You may need to rename the file extension to .zip to be able to extract it.
