This drawer is designed to make use of that pointless cubby to the right of the Ford Maverick radio display.  This fits snug in the cubby hold, making use of the ledge near the outside to hold it firmly in place.  The drawer holder does not require any support at all.  The drawer itself will probably need supports on the overhangs unless you have a printer that handles overhangs really well. The drawer stays closed on its own, however, I did wind up putting a couple of magnets on mine, just so it snaps closed with a satisfying 'thunk'.
