For clipping your Christmas lights to your rain gutter.

I bought a bunch of these at the 99 cent store a few years ago, but haven't been able to find them again since. This year, my box of them vanished, leaving only a few that were still attached to the lights because I got lazy putting them away last year. I needed more, so I drew them up in tinkercad, and ran a bunch off. Posting them if anyone else wants to use them too
