Hooks for christmas lights

This is a hook i designed to hold at least three christmas string lights.
The hook is designed to "hang" on a wall/fence or similar.
The hanger is 12 mm wide on the inside so any fence or wall smaller than this is fine. It is almost 18 cm tall. It is quite narrow(only 5mm) but seems to be holding well.
As you can see in the pictures there is room to hang even more strings on the hooks.
I set my Cura to slice it in "low" quality, that is 0.28 mm since it was not neccessary for it to be a really nice smooth hook. No post-printing work is done.
I printed on my Ender 3 v2.
