This is a 3d printed model derived from MOLA data of Gale Crater where the newest Mars rover Curiousity touched down. Called a "geological candy shop" it has a mountain in the center. Created by taking the MOLA image of Gale crater (http://upload.wikimedia.org/wikipedia/commons/thumb/b/b9/Topographic_Map_of_Gale_Crater.jpg/200px-Topographic_Map_of_Gale_Crater.jpg) and converting the colors to grayscale to indicate depth. The image was then used to create a heightfield from bitmap in Rhino3D, slightly smoothed (there are always artifacts from color replacement), converted to a mesh, the edges extended and sliced off to form a shallow box which was then merged with the surface heightfield mesh. Saved as an stl file, printed at 0.27 layer thickness with 1 shell, 5% infill, no raft or support. Some warping seems inevitable on my printer, but not too bad. At these settings took about 1.5 hours to print.Will pair very nicely with ThePlanetMike's rover (http://www.thingiverse.com/thing:27908). Sorry about the quality of the pic - printing in silver/gray ABS seems to enhance blobs and edges, particularly in photographs. Will try printing in natural and black ABS which tend to photograph better (and melt a bit more easily, reducing said edges and blobs).UPDATE: I just uploaded a much smaller stl file - it has been smoothed (laplacian smooth) with Meshlab. Slightly less detail but much more manageable size. I'll try printing this afternoon.
