Model has 4 quadrants (NW, NE, SW, SE) including Cho Oyu and the north end of Ngozumpa (NW), the southern end of Ngozumpa (SW), and two quadrants to the east including Mt. Everest (NE and SE).

At a later time, I will post the recipe for doing this using data from anywhere. For the time being, I am posting Blender models - as displacement maps and as meshes - as well as the STL files. STL files are scaled for printing on a Makerbot Cupcake CNC with recessed screws. I used all open source tools:
