>>95852728I've made Battletech terrain with mdf hexes. And no, you couldn't do what's in the pic.
It would require hundreds of dollars worth of hexes. It would weigh like 75 lbs. And it's also not really possible to glue that many hexes together with precision. Minor differences in the shape of each hex/hex stack add up, and every stack you glue together pushes things slightly farther askew.
