Below is my entry into Shapeway’s “Co-creator Contest”. The contest involves an entrant designing a template that a buyer can download in order to put his or her own design into part of whatever it is the entry consists of. In my case I revised my Breastplate jewellery and made it bigger (there was a monetary range in the competition). My entry allows the customer to put their own design into the middle of the breastplate outline.
Edit: 15th Aug., 2010, I have created one of these in 24kt gold-plated stainless steel which is available on my Shapeways store for US$70.50, or in White, Strong and Flexible for US$14.23


Full details of the competition that ends on 31st May can be found here: [Update edit: I won the competion!]
