I combined every source I could find, and did a bit of elbow grease sculpting to get a map as realistic as I could.
I'm going to make the buildings, bridges etc as soon as I get some time.

There are 2 STL's included.1) a Skin Only version doe printing near vertically (opt for 30 degree angle off vertical as shown)2) a Box version for printing flat on the plate directly. The box is tal, but you can always make it shorter by lowering it below the build plate (or cutting it to whichever height you want)

The STL's are scaled for the Mono X, but there is no reason you can't shrink or enlarge them to fit your printer.

If there is interest, I'll happily add details and cut it up for you if you want to make a crazy big print. (Assuming you alread bought it of course, this thing took me a while :)
