Thanks to the magic of living in Europe and as per usual, the official camera mount isn't available yet. The choice of camera (eufy Security Indoor Cam C120) came down to a model that I saw recommended by existing camera mount owners and the fact that it uses a USB plug, which plugs into the Litter Robot 4 directly.  

I went with a minimalistic approach as well as having the camera hanging by the sheer will of gravity and without the need for glue or tape on the outside. It can be knocked up theoretically but that does not happen for us and our cats at least.

Also slight changes were made based on the print that can be seen in the pictures, mostly to make it a slightly more snug fit overall. Also strengthened the camera clip arch.

The cable storage happens below the bonnet. Lifting in and out the globe is slightly more involved due to the cable holders, not a huge change ultimately though. Globe still rotates freely.

The cable routing into the holder is best done with the globe removed and does require a bit of fiddling around to find the best length. I used double sided tape to keep them in place. If you don't mind having most of the cable hang outside on the back of the bonnet on top, the cable holders are not necessary at all. Or if you have a better system / idea in mind of course. That was just the best I could come up with.

The black print on our white Litter Robot comes down to not having white PLA on hand at the moment, it does help with the pictures though. 

Edit: also added a pic of how I sliced and printed it using organic supports in 2 places, in case it helps somebody.
