I designed this for the purpose of pulling out the old broken piece that pushes into the door handle and doesn't turn, and pushing in this new replacement piece that will make the locking mechanism of the door handle like new. This specifically fixes the problem where parts of the original turn piece break off or get worn away, making it push inwards and get stuck.

This has pretty tight tolerances within the door, so I recommend using a 0.2 nozzle. I didn't end up trying a 0.4 nozzle seeming I don't think it would print the details good enough, however, you are free to try of course! It prints in about 1 hour 40 minutes, and is just a direct replacement to the original piece. You will have to take off the colored cap and push it onto the new one, it should hold perfectly fine, but if you want you can glue it in place just fine, do it in the slots on the sides. You do not have to use the old colored piece if you don't want, it should work just fine without it.
