A company called Microscape has created 1:5000 scale 3D printed models of city blocks based on aerial scans. Their latest endeavor is a replica of 9 square miles of downtown Chicago.
I know that 1:5000 is much smaller than 1:160, but it wouldn't take much to reproduce at that scale. Imagine being able to assemble accurate replicas of your favorite locations using 3D printing and adding it to your layout! Lots of possibilities! Check out the link below!
