Based on "Customizable Clip Stand" design by walter, and inspiration from "Strong Bag Clip" design by skriver and "Parametric Filament Clip" by qubit01. This part is useful for hanging your phone over something, or for hanging something to your phone, maybe. Who knows :) I think, it functions best when printed with concentric infill. I use .25mm layer height, and it works fine. You can customize it with openscad.
