This is the 10" rack mount for the Unifi UCG-ultra. Has a couple of little holes in the side for passing cables to the front, and fits nicely to keep everything contained and organized. For printing, I just put the front of the model face down and it printed without supports. (Ignore the small marring on the front above the UCG, that's because I printed V1, not v2, where I added a bit more clearance there. Had to cut a bit of that material away. Current model has fixed this but I didn't want to waste the filament).
