Fairy light cable clip

My wife tried to put these lights up with drawing pins. There was a lot of swearing. I designed this cable clip with grabby teeth. I screwed the clip to the door architrave and she could then push fit the cable easily. We can re-use them next year.

I used one screw for vertical hanging, and two for horizontal. If you use something pointy but blunt like a closed pair of needle nose pliers you can really jam the cable in hard without damaging it.

I printed in PLA. I sized for a cable with an outside diameter of 5mm, but the OpenSCAD source file is attached should wish to make a different size. At these sizes the PLA has the right amount of flex in it to spread and grab the cable. I suggest you only make the clip wider for a bigger cable - if the grab arms get to too thick they probably won't flex enough to grab. Too thin and they will snap off.

I have now added clip2.stl - a smaller version more suitable for modern LED lights which generally come with thinner cable.
