I am working on an electronics package to make a ring glow. I have a proto type working. If you would be willing to share your stl files I would be willing to share me electronics parts list and design. See link to image on facebook.
Guaranteed if you take your 3D model, make an account on shapeways, then upload it, set a size and literally print it and have it delivered, I would be the first person to buy this type of style of ring.
