Main Model

The cable clamp is designed for a 6mm cable. I did not include any tolerance to create a wind-proof grip.

I used ABS for outside durability. The model will require a brim if printed in ABS.

Second Model

The 2nd model is something I designed to hang the lights on a 100x100mm metal grid. The distance between the grid was was 95,82mm for me. You can measure that first to see if it will fit yours. The model is also spaced 20mm deeper in the Y direction. This was so that the lightstring clamps hang in a straight line.

If printed, slot the top part over the metal grid first and then push in the bottom (will require some force).

(Quick design, so not parametric, which is why I did not share these)
