To the guys who started this and did all the leg work, thanks! You saved me an easy grand if I would have actually pulled the trigger. I just installed my two cameras today. Found that the nut opening in the 3d tilt bracket was just a little small for the #4 nuts from Home Depot so I made a minor edit to the STL, my updated version is attached. I'm also going to tweak the plug covers slightly just to differentiate between the interior and exterior camera. I snapped the backplate on the exterior camera during install so here's some pics of the interior while I wait for a new one to print.
BTW, the new camera model that replaces the one in the original post works just fine. Also this was all done in a 2023 (refreshed model).
