The Eiffel tower by CheeseJam is great to print since I couldn't print the tower using the origianal version when I scaled down to 100mm height. This version has scaled up details so that I hoped to print, but there is mesh imperfections around bottom arches. So I imported the solidworks file and resave to STL file. It does not have any open meshes now. To some advanced printing software the inverted triangle normals can be corrected automatically, but my own software does not. This model is great and I'll give it a try using my own DLP printer!
