This ring is based off of the Batman Chronicles logo. I designed it to fit a 9 1/2 ring size (.765 in diameter). I have printed this with support material and it works out great. I tried once with the face down and it did not work as well as printing it on its side. -Note- Ignore the "j" in the picture. That was added for a friend who's name has Jake. It has since been removed.After printing there was a minimal amount of support material to take off.Useing the program Inventor, I started with a 2d jpeg of the iconic batman symbol. Then I traced and extruded that symbol onto a ring base. After that it was just a matter of saving it as a stl and printing.
