Vanity Tip-Out Tray Hinge
A print-in-place bottom-pivot hinge that turns the dead false drawer front under a bathroom sink into a tip-out tray — the plastic factory hinges that snap off are rarely sold separately. The 56 mm wide base leaf screws down to the cabinet floor or bottom rail with four #8/M4 screws (4.5 mm clearance holes), the 25 mm leaf screws to the back of the panel, and a triple stop wall gives a hard 90° closed stop so the front sits flush; footprint 56 x 66 mm, 22 mm tall, print two for one front.
