A simple string light hook with a countersunk hole for attaching with a self-tapping screw. The screw pictured is a 6G 25mm wood screw.

If you're looking for a hook that attaches to ridge lines, like the top of a fence or railing, please see my String Light Ridge Hook model.

The hook has a curved transition into the large radius to ensure it is flexible and strong. It is designed to be printed on its side so that each layer consists only of walls running the length of the hook (see slicer pic). The screw hole prints fine without supports. I printed in Bambu PETG HF.
