I made this a few days ago,
One, I wanted one with a hook so I could put my keys when I get home.
And two, I made a blank one for around the house, no one had the big style and a blank on the side.
It's a bit more square, I don't like them round.
Technical
I printed in PLA white, seemed to come out nicely.
I did use supports for the hook, and you may need them, depending on your printer, but make sure they are on the side that won't show. Or use very thin supports so you can break them off cleanly.
