Custom shapped cookie cutter. Also can be used on other materials like clay or Play-Doh. Just draw a picture on a piece of paper, or your computer or iPhone, and send me the image. I'll create a cookie cutter shape for you.
Visit my Sheltie shaped version here on youTube so see one printed in Aluminide. http://www.youtube.com/watch?v=lgoOA82qF-Q
