I am a mechanical engineer specializing in new product development. Im relatively new to Shapeways and I just recently uploaded a new design for sale; in the form of a helical gear shaped ring. Ive seen many gear type rings but something about this design really got my attention. I used a comfort fit on the inner wall and a small radius around the outer edge. Its really comfortable and so far Ive had alot of compliments. Having never really worked in jewelry Im interested in any feedback I can get. Please let me know what you think. Available in silver (standard and glossy) as well as stainless steel. Thanks, Lyman Lyman Bishop www.star-labs.com
