The Mach Loop is a series of valleys in the United Kingdom in west-central Wales, notable for their use as low-level training areas for fast jet aircraft and propeller-driven aircraft. This was downloaded from http://jthatch.com/Terrain2STL/ great piece of kit, the pictures are oriented North to south as the first one, the aircraft usually come from the north and weave down the valley. Scale and print how you like. Mine printed at .15 and 20% infill, had a small issue with warping but still looks good. Thanks for looking.
