Summary

I wasn't seeing a hook that met my needs, so I modeled my own based on kludgemonkey's. I wanted it to have a semi-snug fit on my gutter and to snugly fit the thin LED wiring (I have 32v LED's, not 120v). I want my light wiring to be taut. My wiring is 1.5mm thick, and the depth of the gutter is 14mm (.55").

I recommend PETG since it's good for outdoors.
