Hi, I am a CNC enthusiast and make files for carving.This file was created from free height map data found online with free editing and modeling software. You can make your own if you have time to learn the lengthy process or be lazy and buy this one.
If you buy the file I will happily discuss milling strategies I have found effective on my machine. Only avalible in STL format. I do have all the states if you're looking for a different one. I can probably manage any region/country relatively easy. Please drop me a message if you're intrested.
Thank you,UNA
