Again, pret-ty specific, but hey, we're sharing here :)
This is a hook I made to mount an old school fly screen that didn't come with any materials whatsoever to actually attach it above the door. Once printed normal and once mirrored.
I know not many people will have the same exact fly curtain (also I don't remember the brand name), but it might give someone an idea.
