Howdy,
I am new to Sawmill Creek (and my laser engraver) so this is my first post. I had to teach a lesson on reading a topo map so I scanned a topo of Mt Washington. I cut the elevations so they stack so students can build it like a puzzle. It is build on a piece of plywood that has the top engraved on it to help see how the paper map translates to a 3-D image.
No idea how to sell it but it was fun to make and watch people play with.
