I made a USB hub holder for the side of my desk at work to give me more desk space, and so I could plug things in one handed without the hub sliding around. The opening on the desk side is 30.4 mm (1.19 inches). It holds a Sabrent 4-port usb hub, either powered or un-powered. The USB ports will face upwards (or down if you mount it that way) and the button are on the outside
Be sure to push the buttons down before inserting into the holder. The tolerance for the hub is pretty tight so it won't move around within the holder.
