w123 door lock assembly with 3D printed component

I had a friend make the component for me. It's the bronzing colored part that swivels. They typically break on a passenger door lock and then you cannot lock or unlock that door with a key.

Had that piece break on the front passenger door of my '84 Euro TD. It was plastic. Wonder if the 3D replacement is stronger than the original.
I replaced my latch assy with one from an early W123 which had that part made of metal but was slightly different design. Had to modify the key-lock shaft a bit to fit the early latch.

Happy Motoring, Mark
