I needed to mount a new Unifi Protect G4 Instant Camera on a wall, but I need the camera turned to view sideways along the wall.
I found a suitable wall mount on Thingiverse by darklis: https://www.thingiverse.com/thing:5393420
Unfortunately, the 22.5 degree angle on that mount was pointed in the wrong direction for my needs. Therefore, I rotated the top by 90 degrees. I also added a cable channel for the USB power cord to run out the side. I recommend adding supports for this section as my print sagged a bit over the channel. I eventually cut out the sagging bits as I didn't need them for my application.
