The file 'Texas (trimmed Coastline) 3D Printer Model' is (stl) file type, size is 1.3MB.
I just trimmed the Texas height map to sea level and exaggerated the elevations a bit so it will show up better in your prints.
This was done completely in the Netfabb desktop application. I adjusted the Z axis to remove the ocean water layer and then added a few mm to the Z layer without changing x and y, which stretches out the visible peaks a bit.
