Fridge door shelf bracket support
Refrigerator door shelves hang on small plastic supports that go brittle in the cold and crack under a full milk carton. A replacement support is a 40 x 25 x 30 mm bracket with a hook that engages the slotted door liner, a horizontal ledge with a 3 mm lip that carries the shelf, and 3.5 mm walls to handle the load. Fillet the hook root generously, because that is where the original failed. Print it hook-up in PETG, which stays tough at fridge temperatures where PLA turns glassy.
Every liner uses a different slot spacing and hook size, and SpeakCAD models the support from your measurements so it clicks into your door. Need a mirrored pair for both sides? Ask in the same conversation. Trying the design in the browser is free.
