An adapter plate for the Apple Cinema Display (30 inch). This is so you can use one of these old chunky monitors on a more useful stand! You'll need to remove the stand that comes with the monitor, and save those two fancy looking screws on the side. You'll also need four M4 nuts to use in the screw holes on the adapter itself, Made out of pla plus i can also make it out of petg/abs/nylon but message for a quote on price for those please Shipped the next day!
