I happen to have a printer that does something like 14”x24” prints, if you can find one you could do a little SVG hex map or the like and tape several together.
I don’t think 3D printing the individual hexes would work out cost effectively, although if you had a laser cutter wood hexes might work out…but not if you ALSO have to buy the cutter.
Oh! In the states Staples and other office supply shops will print “posters” from your source material. If you make a PDF of the map you could get some place like that to print the “poster” of the map. Some of the material can be very durable. Some places also “print” blankets or throw rugs. Any of that might work out at an OK price…
