Here is my take on a Chess Board.

I printed this with my Bambu P1S with AMS system so it can print the black and white squares while the base is plain gray. I printed the borders in brown.

This chess board is separated into 4 sections so even smaller printers can print them. I can only fit 3 tiles in my p1s. Same with the border pieces, only 3 at a time. Kind of frustrating.

These use OPTIONAL 3x2mm magnets to stay connected but a decent nudge will split the board. So I added an option to add toothpicks so that when put together it'll stay intact a little better.

I added a picture showing the polarity of the magnets, these are set in a way so no matter what face you put together, it'll stick. Basically on a given face, put the north side on the right, and south on the left. You can take a minimalist approach and just magnetize the ends of the borders. I hope this makes sense because I'm unable to explain it any other way.

For my patreon subscribers I'm planning on making different (skins) for the borders. Currently planned borders are a graveyard border, and a grassy border. This free one I just labeled as the (classic) border.

And finally, these tiles can be doubled as dungeon tiles. Depending on the tile system you use, these will obviously just sit next to your dungeon tiles and won't connect in any way. Unless by some chance your dungeon tiles use the same magnet system I'm using here. These could be good to use as a secret room that you put off to the side when someone finds a secret trap door or something. The other tiles I'm using for this example are the Dungeons & Lasers Tiles.
