Hey Heff, were they carrying any load, if so maybe later I can pick your brain a bit for help then? I'd prefer PLA if I can, simply because it's more environmentally friendly but I could not print anything that would survive being inside a car while holding any sort of weight. MY outside camera mounts were the same even if they are not inside a car. Maybe I'm not doing it right.
