Unifi Ultra Cloud Gateway rack mount
I just got the Unifi Ultra Cloud Gateway and could not find a rack mount. I downloaded Fusion 360 and built my own. It is probably using too much filament, I went a bit heavy but will at least be solid.
The UCGW is blocked in the back, you can pull it from the front. You could put a bit of double-sided tape to keep it in place, although not needed.
I am now working on adding a Raspberry Pi on the left as well as RJk5 keystones. I remixed the design from https://www.thingiverse.com/thing:4098207 and added 4 keystones next to it so that you can plug your Raspberry pi + 3 ethernet from the cloud gateway ultra. Had trouble printing this part. I would recommend printing it without support and just stop once it starts having issues printing the back of the RPI case. I did not need it myself - it is hidden in the rack.
