Unifi USG and Cloudkey Rackmount

I really liked the original design for the USG mount by Gigante. It was exactly what I was looking for aesthetically, and I liked the modular design where panels could be mix-and-matched.
The original worked well mounted directly above my switch, but when I moved it above a patch panel where it was unsupported it sagged down on me.

This remix was my solution. I added some extra support to the original shelf design. Added a blank panel with reinforcing ridges for the middle. and lastly, I added a panel for the Cloudkey Gen2 (which is a remix of https://www.thingiverse.com/thing:4609160). The USG has very little sag now.
