I designed this ring using Tinkercad. I happened to have gold and black paint on hand and it turned out just as good as expected!

Some things you should know:

1. Print using the highest resolution possible for best results

2. You will probably need to play around with the size to get a proper fit

   If you do print this ring and and paint it, feel free to share your designs in the comments. I would love to hear about your ideas!
