I needed some bag hooks for my Ford Maverick, so with a little bit of trial and error I came up with some that fit nicely in my OEM Bed Track system (I'm assuming that the track system is the same across all Ford Trucks, but haven't tested them yet). Simply slide them in sideways and twist, they snap into place and are more than strong enough to hold anything I could put in plastic bags. They are strong enough to hold a 20lb bag of potatoes easily. They don't slide with any weight on the hook so you don't have to worry about your good sliding back and forth.

Do not print these out of PLA unless you want them to start dropping your bags in the sun one day. I've printed these out of PETG, and ABS and ASA should work fine also.

Print with at least 4 walls and heavy infill. I did these on my Bambu with a 0.4 nozzle, 5 walls, and 40% triangle infill. I would think that anything with 4 walls with at least 25% infill would probably be fine, YMMV.

This is an original creation of mine, but make all you want for yourself and your friends. I have them up on Etsy for those who don't have access to a 3d printer, but I don't want to catch anyone else selling them.
