Count not find a good hook to hang the loose plant branches in my room. Oh, yeah, this is exactly why I have a 3D printer, right? I just put some adhesive tape on the back and here you go a lightweight hook, strong-enough to hold a few branches or even a whole plant (just make sure to get good tape). Feel free to remake this any-which-way you like—I've provided the Solidworks source file for you.
