My wife wanted a hook that screws in, instead of doble sided tape. They eventually fall off. But, she wanted something that's “pretty” but simple. So, I made a generic flower hook.

Prints in two pieces, then you put the screw through the hook and the base. You might need to drill out the hole a bit. I'm sure most people will use random screws like I do. lol I'd say use at least 3 walls with a .4 nozzle, on the hook. And say, 25% infill of your choice. (I went Gyroid)

A simple color swap on the right layer, works wonders. That's all I did.

This hook is just holding up a ton of plushies. (actually like 5-10 pounds) I wouldn't go much more than that. But if you break a hook, that's all you have to reprint. Saves on material. Mine is printed cheap Creality PLA. $15 a spool I believe.
