This is a power shroud for the Xbox One Kinect. There are a few ones out there, but frankly, they all suck. Except for the Abyss Shroud.
However, the Abyss shroud isn't available, except to by already printed. No STL files that I can find. So I made my own, with some improvements on the Abyss design.
Fits the two Kinects I've fitted them to just great.

With this shroud, you won't have any funky power cords hanging off, and your USB3 cabel will fit nice and snug with no slop.
This shroud is designed around a 2.1 ID 5.5 OD barrell connector. Specifically, I think I used this one:
Not 100% positive on that, though, as I just used what I had on hand.
