NOTE: Use V2 for a better fit. All pictures, except for pictures showing how it's mounted are now of V2 instead of V1
This model is to fit 70mm Morimoto XB LED Fog Lights on a Volvo P2 R.
I bought my R bumper without any existing fog lights, so I did not even have the factory mounts. I struggled to find the factory fog light mounts for a reasonable price anywhere and didn't want to purchase a kit with factory-style fog lights and mount since I knew I would want to upgrade to LEDs.
This design ended up looking a bit janky since I had to do a lot of prototyping and test fitting before getting the final result. It works really well despite the strange look. I also added to the design to make these as secure and durable as possible.
Take a look at all the pictures to see how this fits. As shown in some pictures, due to the shape of the factory fog light grille, one side of the light sticks out through the hole and the other side still sits behind. This isn't really noticeable when casually looking and doesn't have any impact on the beam. V2 is significantly improved over V1
I believe I used the factory fog light mounting locations using the pegs and two M4 nuts and bolts. One of the images has these screws circled in red and another shows the view from behind. I used loctite on all the bolts for this application.
Print in the orientation shown in screenshot and definitely use supports. I used a lot of shells (I think 8) and 60% infill for increased durability.V2
I uploaded V2 (pictures coming soon). This basically rotates the light mount 17.5 degrees towards the outside edges of the car and makes it protrude a bit less. This fits the curve of the grilles much better, but is still not perfect.
