Summary

Topographic map of Washington state based on a TouchTerrain model. I've removed islands (for printability, sorry!) and the borders are basically hand-drawn. And I had to exaggerate the z-axis to make everything visible. Otherwise, it's pretty accurate!

Print on the highest resolution you can manage unless you want thick layer lines. Stringing is a problem in the valleys, so consider lower print temperatures or blast the finished print with a heat gun.
