I need a file for a 3D print I will be making

I want to print a dream catcher design I have the materials I just need to get a photo transferred into an stl file so that I can print it. It will be 6x6 inches across and 2mm thick. I will attach the image so you can see what I’m thinking. Hopefully you can make the lines a little cleaner too. I hope to hear back from you thanks!
