This print allows you to mount your Dell docking station for to the underside of your desk, the wall, or anywhere else. Two screw holes mount the plate to the wall and then two 2.5M screws attach the knobs to the docking station. Slide the knobs into the slots and slide down to click in and secure. Releasing is quick and easy and doesn't require removing any hardware. Originally designed for the Dell WD19DCS model but should fit any Dell dock with the 89mm screw spacing.
