I made this because I was bored of how plain Memoir '44 looked, so I thought adding some terrain risers would give it some more depth.
It comes with two files, a 6mm riser (best for hills) and a 9mm riser (best for mountains). However, obviously, you can use them however you want.
After many trial and errors, I got this version which SHOULD work very well. Otherwise, I'm going to measure a hex myself with a caliper to get the exact measurements.
I have yet to print and test this new version, so until then, it will stay as a Work in Progress.
