Green Lantern's ring

thingiverse

Please review my revised Green Lantern ring based on the movie. Check out this improved design for better accuracy: http://www.thingiverse.com/thing:753155 These are the build instructions. The ring diameter measures 20cm, so if your finger is sized at 20mm, simply scale it down to 10% and print. I personally printed mine with transparent PLA and highlighted it in green with a permanent marker.
