This extra-large chessboard is designed for the famous medieval Lewis Chess Pieces found on the island of Lewis in Scotland. There is a set of these modeled at Thingiverse by user nestra:

According to the British Museum website, the original pieces are massive, with the kings averaging about 95 mm high (3.75 inches). A standard board is not big enough to play with a set printed at an accurate size. So behold, this design.
The board is split into 4 equal sections about 10 inches square, and is contained by a decorative interlocking border that keeps everything together. One board and one border can fit on a Prusa XL printer bed, and the print can repeat 4 times for a complete board. The board can work without the border, but you need a way to fasten the quadrants together (archival linen tape on the underside, for example).
The design is a minimalist take on an abstracted Celtic knot. The detailing is designed to account for printing large flat top fill areas. I tried a couple of different patterns and preferred Concentric in my final print. I tried ironing, but it was not a good look.
Chamfered channels are built into both sides of the board. The channels on the build plate side act as expansion joints, ensuring a dead flat print without using brims or helper disks. I've had excellent results with this technique.
The border interlocking mechanism features strategic chamfers and a draft angle to ensure a snug fit. On my third design iteration, I got one that snapped together well without sanding or filing. Your mileage may vary: let me know what your experience is if you print it, and I'll attempt an alternate design to account for any difficulties.
The images include a rendering of the model, an exploded view showing assembly, and a set of Lewis chess pieces on the board both with and without the border.
I strongly recommend using the multi-material capability of the Prusa XL (we have a 5T in the shop, but a twin extruder would work just as well). I printed in black and brick red PLA using rectangular infill with 0.2 Structural setting, no brims, support, or helper disks.
Final note: of course it’s possible to scale the file to fit a Prusa MK 3 or 4. You can get a smaller-than-standard 16 inch board without the border this way.
