This is a part to replace an existing vend motor switch arm in a DNCB 440/252-8 soda vending machine. Please see picture of it installed. It was printed in PETG atomic filament marble v2. It is the grey switch arm in the picture. This is from a DNCB 440/252-8 which appears to be an early 1980s model.
