Print with no supports both the hook and the scooper, I used 0.3mm layer height, 2 perimeters, 3 top layers, 2 bottom layers and 10% cubic infill.
Mount the hook on a wall with 2 screws, and place the scooper on the hook when you're done scooping stuff.
The shorter hook is slightly faster when you grab the scooper, the longer hook feels more satisfying but this is nitpicking.
The author remixed this model.

I've recreated the original design from scratch in fusion, it has different dimensions, a thicker handle, and can be wall mounted on a hook.
The hook has two screw holes and I originally made it to hold my phone on the side of my bed, and when I saw the original design i thought, this would work well with my hook :)
