X/Y scale is 1:50000, Z scale is 1:10000 to make it easier to visualize the terrain.
I made this using a QGIS shapefile and Rhino. I used the patch command, so there is some deviation from what you'll get if you triangulate the points, but then again, there will also be a deviation between a triangulated model and the real world so in the end it doesn't matter that much. It would be nice to use the same method to generate a larger model to be made in a CNC router, but since my CNC router isn't finished yet, this works quite well as a proof of concept.
I believe models like this would be great for a topography class.
Printed in ABS with a 0.8mm nozzle, 0.4mm layer, forgot to turn on retraction.
TODO: make a PETG chocolate mold from the model using vacuum forming.
