I had existing cup hook around my porch for hanging decorations from, but they were too small to place a rope light in. This clip hangs on the cup hook and provide a clip for the light strand. Print as many as you need using ABS. For grins, I used a glow in the dark ABS for these clips. Choose an infill you feel comfortable with. I used 20%, though the portion that actually uses the infiltration is very small.
