An apparatus comprises a tray including a plurality of radial openings. An inner tray support and an outer tray support are connected to the tray using a fixed connection that allows the tray to pivot within the inner tray support and the outer tray support. A spring-tensioned ball catch is configured to provide the tray a slip-locking connection through the plurality of radial openings of the tray that allows the tray to be rotationally adjusted within the inner tray support and the outer tray support.
