Summary

The cable company left one of these stuck in my vinyl siding. It basically just clips up in the gap at the bottom of two segments and will route things like outdoor lights, CATV coax, phone line, fiber optic, etc.

I liked it so much that I recreated it in Fusion 360 and have now printed more than a few to hold some decorative lighting as well as network cabling. They seem to work well if printed in PETG or ABS. I recommend printing with the flat feet against the print bed for maximum strength, even though it means you need some small supports under the two small arms.
