I broke a home store kitchen cabinet shelf clip. It was easy enough to CAD and recreate. Easy print. STL is already in the correct orientation to print. No supports needed. I printed mine with 4 walls to make it stronger.
Nib is 1/4" x 5/16" (6.35mm x 7.5mm). Back is 1" tall and ½" wide.
I do not know how much weight it can handle, but I am sure it would be close to whatever the original was capable of.
Enjoy!
