It has been a while but I think I printed it with the visor/front screw portion down and used supports for the portion of the body which doesn't touch the build plate.
The camera must be inserted before mounting (as I mentioned, lots of room for improvement).
The author remixed this model.
Thanks to RT3D for a great model! Added a sloped portion to the top for ceiling mounting with a downward viewing angle. Regarding my changes, there is plenty of room for usability (mounting ease) improvement but it's been working for the last 6 months so I've not taken the time to do so. I've only mounted with one screw.
