I wanted a phone holder that would stay out of the way by hanging on the edge of a shelf on an Ikea Jerker desk, so here it is. Picture shows a Pixel 6A.
I printed with 5% infill PLA and it seems sturdy enough.
I made a variation that sits a little higher and has a slot for a charge cable along with a bottom lip.
Both are included in the attached blender file.
