This is a "blank assembly", left side, for Monroe K- or KA-series mechanical calculators, which were manufactured between 1920 and 1928. It is used on the blanking shaft assembly to zero out the keyboard. In the M-series, this is part number 30-822, so let's call this part number K30-822.I used SolidWorks for this. Print the STL at 1 unit = 1 inch.
