I designed such brackets for my OEM fog lights (OBEN for a 99) some time ago. They fit and got the job done until one cracked due to poor layer adhesion; For temperature tolerance I printed them from ASA which has a high glass point. I plan to make another set with as sparse infill as possible then hollow them out and fill with epoxy for strength. My Jeep was my daily until I accidentally turned it into a mess of a project so I can't say these fog light brackets are high up on my priority list, but if you're open to doing some experimentation, I can print you two sets, one with maximum and one with minimum infill, for you to play with. You'll have to paint them if you want them black.
