I designed and created 5 ring shapes and, in this Instructable, show you how to customize them in 123D. Even if you're like me and don't have a 3D printer, you can still customize your own ring shape and in a few clicks, send your design off to be printed. I've included all five designs for you to download and customize. There are STL files attached and links to the models pages in the 123D Gallery.
Here are the rings and I've numbered them 1-5. You can download the files here. I've attached STL files and also included hyperlinks below so you can download straight into 123D and start customizing your ring right away!
I'll be using ring design #5 to show you how to personalize it with your initials.
