Iztaccihuatl is a dormant volcanic mountain in Mexico. Constructed using 1 arcsecond resolution SRTM data from the Space Shuttle (about 1.4 million polygons). It was made using a new and, as yet, unreleased version of SRTM2STL. The source code for creating files at 3 arcsecond resolution is available up on github under the GNU license. Go to github and search for SRTM2STL.You may want to print this to be relatively small. I get warping using PLA and it gets bad when I try to print Raised Relief Maps that are big. I have had 'some' success with big maps. If you have a way to control warping you may also have better luck with big maps.
