Jeep Headlight Receptacle

This is my revision of part Chrysler 5012685AA which is what the ball joints on the rear of 1999-2004 Jeep Grand Cherokee Headlights fit in to which help the headlight stay in place while allowing the housing to work with the angle adjustment screw. There are three on each side and printing all three worked well. However, I think in design I anticipated a little more shrinkage than I actually got. So if anyone else prints and uses these, try printing slightly smaller, perhaps 1-2% smaller.

The main question I now have is whether or not printing these parts in PLA with allow the part to misshape due to engine and environmental heat.
