Synopsis: Refrigerator door stopped closing on its own and eventually the bottom of the shelf thing started scraping the liner at the bottom. Diagnosis revealed that the two-part door closing cam system at the bottom-right door hinge assembly had worn down to the point of failure.
Solution - partial. I am only uploading the model for the bottom part of the door cam. The top part is cheap from online appliance dealers, but the bottom part is only available as part of a more elaborate hinge assembly (adjustable hinge door). I will eventually post both parts, but I would prefer to recommend buying one part and making the other. Why? One part will be super hard and smooth. The other part if printed on FDM at least, will have some layer lines. Printing with 7 perimeters makes the contact surface solid, and if you lube the two parts before replacing them, you'll be fine. My worry is that two meshing parts with layer lines will not work as smoothly. By replacing the unavailable bottom plastic cam, and buying the smooth top part ($7 in USD + shipping - part # for top section shown) you can get the happy middle ground.
Printing instructions: 7 perimeters. 40% infill. PETG or ABS.
