Hanger for stackable bins

This is a hanger that you can attach to the edge of your table so that you can hang stackable bins off of. I use these on each side of my reloading presses.

I used PLA+ but i'm not sure if you could use PLA or PETG. I used 5 walls and %30 infill but i'm very new to 3D printing and I don't know if that is needed for strength.
