42″x42″ custom printed diplomacy map (Help please). – January 2, 2023 at 07:08PM

I want to make a larger map for my in-person Diplomacy game. I want to give some gravitas to the game so I am going to get 3D prints of the pieces to scale up with this map. My table is 42 inches on its shortest dimension so I think Diplomacy is a square map so 42″x42″, unless it isn’t then I would make 42″ the narrower dimension so it fits on the table. I was thinking neoprene map. Can anyone suggest where to get an image to scale up to the correct size? Also any experience with mat printing services you can recommend.
