Yosemite Valley's Cathedral Rocks
thingiverse
A highly intricate 3D topographical model of Yosemite Valley's Cathedral Spires is available, showcasing the ledge on Lower Cathedral Spire's classic climbing route. The model was created from a LIDAR dataset obtained for nitrogen export research and shared on http://opentopo.sdsc.edu/. It was gridded to a 0.5m resolution. A tutorial video is accessible at https://www.youtube.com/watch?v=bzwybr65I9o, where it's mentioned that the print took 18 hours and was sliced using Simplify3d at default high quality settings on a PLA printed FlashForge. A crack occurred at Bridalveil Creek's base due to lack of infill. Alternatively, there's a model focusing solely on Cathedral Spires area available at http://www.thingiverse.com/thing:285873. The 3D Printing Today podcast (iTunes, Stitcher radio or direct from the source at http://threedprintingtoday.libsyn.com/) featured this model.
