A Simplistic Moon Ring

I was playing around on TinkerCad and decided to make a simplistic Mako Mermaids Moon Ring. (I'm a beginner to 3D Models) That's about all I can say, I haven't tried printing it. If you print it, I'd love to see how it turned out! If you have the time, please take a few pictures and add hit the button that says, "I Made One" so we can all see any issues that occurred, or simply remix it and explain what was wrong with it. Thank you so much for enduring the long description I've written.
