Since my printer is not infinitely big, the game board was printed in pieces and assembled with glue. However, it is in theory printable as a single piece. This was a design decision to see if it would work, more than one that was the best choice for the medium. But still, I think if this was scaled down to a "travel-size" version of the game, you'd get good results. Unfortunately it's designed in TinkerCAD so I'd need to start from scratch for such an endeavor.
If you want to print the board, you will need to cut the board into chunks like I did for your printer and then glue them together. Unfortunately, you will find that it's difficult to create perfectly flat sheets of plastic with a 3d printer.
