3D model description

This is a 1:10M scale of SRTM 90M elevation data with a 10x vertical exaggeration.

This is way harder to do that it should be. I'll document it when I figure it out and get a decent printable model.

3D printing settings

This is a rough outline of the steps used to create the file, mostly from the following guide: https://dl.dropboxusercontent.com/u/11089897/3druckench/maps_to_3D.pdf

Download 3DEM from http://freegeographytools.com/2009/3dem-website-is-gone-but-3dem-still-available-here
