Rackmount ears/shelf for 7.5" switch and Unifi USG

While this is an all original design, I definitely received ideas from several other similar designs here. Sadly, I can't figure out how to get the remix search to match. The two designs I most looked at were:

I am new to 3D printing and this is my first design, so it is probably much more plastic heavy than it needs to be. I printed the "non-thin" version but after printing one of the two pieces, I realized I could probably thin the ears some and reduce the protrusion from the rack without sacrificing strength. This would be especially true if this is sitting on top of another device. So while I have not tested the thin ear version, if I were doing it again it is what I would use.

The switch that I am using is 7.5 inches wide. There seem to be a good number of generic switches in various configurations that are in this same form factor.

The exact switch is https://www.amazon.com/gp/product/B0899CMJ14 but a search for "poe switch" on banggood or especially on aliexpress shows many others in the same case. I have included a picture of the label on my switch in case it is useful to someone.

I included the Fusion 360 file, it should be fairly easy to modify this for devices of a different width.
