Green Lantern inspired ring.

I crafted a Green Lantern ring for my buddy, originating from a size 13 template, so if you're a different size, you'll need to resize it accordingly. On the white printed version, details can be tricky to spot, but it's essentially identical to the green one. Some minimal support is necessary, and with thick walls, 30% infill, and a layer height of .2 mm, printing took roughly ten minutes.
