Lincoln MKC New 3D-Printed Cargo Net Hook

 It was bound to happen. A plastic hook in the cargo area of our 2015 Lincoln MKC somehow broke. There are two of these hooks that are used to support a cargo net. I looked online and it appears the only way to get a new hook is to get a whole new cargo area side panel. That's not going to happen anytime soon. So... what options do I have? I could glue on a piece of plastic to the the remaining flat part of the hook but it probably wouldn't hold up too well and not look too appealing. The second option is to try and design a new hook and print it out on the 3D printer. The first photo below shows the hook that is not (yet) broken.

The hook fits into a plastic housing that is fastened to the carpeted panel in the car. I used Tinkercad online to design the new hook. It took a bit of trial and error to get the hang of using the program, and it is all online so I had to create an account to be able to modify the part in the future if needed. The below image shows the major parts and cutouts.

This next image shows everything grouped together.

Once the model was created in Tinkercad, I used Cura to do the slicing and set printer parameters. I used PETG filament, running a nozzle temperature of 240 degrees C for the initial layers and 235 degrees C for the remainder. Bed temperature was 80 degrees C for the first several layers, then heat was turned off.

This next photo below shows my first several iterations, with the broken hook on the left, then the first try next to it. I failed to turn on "support" on the first try, so it was a minor setback. The glob of PETG in the middle was the second try and where I tried to use a higher print quality, but obviously something went awry. I wasn't monitoring the progress, so it was almost "done" printing when I realized the problem. The hook on the right is the fourth try (the small chunk was the support webbing for the actual hook).

Two more tries and I finally got a part that snaps in place and works well without any trimming or sanding.

Below shows the hook installed and open.

And here the hook is in the closed position. It's not completely flush when closed (and not quite the right color...) but I'm not going to bother trying to tweak the model to fix that small deficiency.

The black carpeted panel (and maybe the upper white panel) is what needs to be purchased from Ford/Lincoln to get a new hook. Unbelievable.
