Catacombs of Karak is a great game full of emotions. Sometimes these emotions turn into dangerous movements and can distort cards on the table. This 4x4 grid helps with that.
And oh yeah, its stackable and connectable too!
You can use it with Karak or Carcassonne.

I used PLA, but pretty much any 3D material will do just fine as long as it doesnt warp.
After printing, just cut off the small brim between the connections (see final look of the part in the photos) and enjoy.
I also included a 3x3 version for smaller printers such as Prusa mini or A1 mini.
