Christmas Light / String Light Railing Clip

My wife wanted a quick and easy way to string up some xmas lights on the front porch railing.  She found some plastic clips online, and of course I immediately said “I can do better than that!”  I modeled these clips from scratch in tinkercad.  Just bend them a bit to clip onto the railing or any 2" nominal (~1.6" or ~40mm, in reality) piece of lumber.

Note that lumber is not cut with strict tolerances, and your 2x4s might be a bit thicker or thinner than mine.  I recommend printing one clip to test fitment, and scaling the rest by a few percent one way or the other if needed.

Printed in some generic ASA, which seems to work great.  PETG would also work well.  You want something with a bit of springiness to it.  PLA might be too brittle - especially in very cold weather.
