Hanging Hook for Storage/Trunk

I made this in Tinkercad so that I can have hooks that attach to my Rago Fabrications shelf and allow me to support/hang shopping or grocery bags to keep my groceries from rolling around the storage area of my 4Runner on my way home from shopping. These have come in very handy, and I've made many sets for friends and family.

Development History

v1: Initial proof-of-concept. Sloppy, ugly, but functionla.
v2: Made body longer, smoothed out.
v3: Removed curved cross-section, lengthened top of hook
v4: Rounded off edges

I recommend printing these in PETG. I printed them with 50% infill and I tested the strength and they supported a 45lb weight without breaking (static). Dynamic load will likely be about half of that.
