14″ x 14″ model of the Lunar North Pole. 608.1km square. The view is from the farside looking back toward Earth. Roughly a mile per millimeter. The scale is equivalent to a lunar diameter of two meters. The bed of the prototyper is 10″ x 14″, so this is made of two tiles 7″ x 14″ glued together. If you try this at home with a binder-based media, be very careful gluing. I managed to rub out all the detail along the seam for 80 degrees South, and will have to run them again. As it happens, a 4 megapixel file crashed the kernel of Mathematica when exporting as an stl anyway, so it was a good opportunity to split the file in two and run both halves sequentially.
