St. Louis Gateway Arch

Updated Description: This is a precision model of the Gateway Arch in St. Louis, Missouri. The STL file scales down 1 millimeter to represent 1 foot, while the Thing file has been further downsized to fit my printer's capabilities. I referenced a detailed explanation of the arch's mathematical design and utilized this knowledge to recreate its structure with pinpoint accuracy. As a Mathematica user, I found the formulas provided invaluable in streamlining my design process. The cross-sectional profiles of the arch are formed by equilateral triangles that vary linearly according to their altitude from 54 feet on an edge to 17 feet. These centroidal points lie along a weighted centenary curve, ensuring the total height equals the total width. Initially, I created a standalone model of the arch atop its base. For the revised version, I modified the base to resemble the entranceways to the visitors center located beneath the arch. Additionally, please note that the elliptical grass patches are not accurately scaled, as actual grass does not reach 5 feet in height.
