Updated Description: This is a scale model of the Gateway arch in St. Louis Mo. The .stl is at a scale of 1 millimeter equals 1 foot. The .thing file is scaled down from there to fit on my printer.

The cross sections of the arch are equilateral triangles that vary in a linear fashion with the altitude of the centroid from 5
