Christmas Lights Railing Clip (Sponka na zábradlí pro vánoční řetězy)

I used to wrap my Christmas lights around the railing beam, but now I just clip these little prints on and hook the wire. Easy to use and cheap to reprint next year.

I think the 3×3 cm beam like I have is the most widespread, but I also provide other dimensions for square cross-section beams.

The clip is best printed in PETG for flexibility and resistance to the outside elements. Given that this is primarily intended for Christmas lights, UV exposure won't be that much of a factor, but still nice to be ready.
