This is a zero digit keystem for Monroe K- or KA-series mechanical calculators, which were manufactured between 1920 and 1928. The keystem for the nonzero digits are different than this! I'm not really happy with the way this turned out in OpenSCAD, since I don't know how to do bends in OpenSCAD, and Blender is beyond me. If you have a metal brake, you can print the nonzero version of this part, and then see the bending instructions there. Instead, I did this in SolidWorks :(1 unit = 1 inch in the STL file.
