This is a simple hook to hang garden tools. The opening is 2cm wide and 3cm deep and the top is angled 2 degrees upwards to keep the tools from sliding.

Edit: I also added a version that is 3cm wide, since a couple of my tools had a wider base.

I printed it in PETG with 4 perimeter walls and 25% gyroid infill. Make sure to use the “lay on face” feature of your slicer using the top face (the model is already oriented with the top face towards the build plate). You then can print it without supports.
