3D Printed campaign maps

I made a realistic version of Icewind Dale for my Rime of the frostmaiden campaign 😁 I'm starting curse of Strahd soon as well, so have made the stl but haven't yet printed it. Have a render instead!

Any thoughts on other campaign maps that would work well? I've been avoiding cities so far as I can't think of a smart way to place each individual building. I use Gaea to simulate the erosion details, anything that's too great an area ( more than 50x50 miles) doesn't work so well.
