Curtain Hook

New to 3D printing and wanted to start by tackling simple household problems. The curtain in my living room is too heavy for the rod it hangs on so it droops in the middle. The the rod only came with two hooks for the ends so I made this and it has been working well for about a month and half now so I thought I'd get it out there and see what others thought about it.

Diameter of the rod hook is 5/8", .625", roughly 15.8mm.
