I discovered this part was broken on a family member's car causing misalignment of the bulb. A few prototypes later this is what I ended up with.
Seen here printed in PETG which failed! The PETG melted from the heat in the end.
I replaced it with PA612-CF, annealed after printing, which seems to be holding up to the heat.
Printed with supports as the bottom is not flat. The bulb positional stops were a bit long in my case and were trimmed after printing with a pair of wire snips. The fit otherwise was very good and installed without other issues.
The author marked this model as their own original creation.
