This link is one I made and it will take you to Shapeways 3D printing website. The link was very long so I shortened it in Chrome.
The designer (I think) sells 10 pieces for 20$ and if you use the search you might find moresellers.
Oh and here's the link: http://goo.gl/LLE3d6

I'm not connected in any way to Shapeways or the designer. Just sharing something interesting.
