Takes forever to get in contact with anyone. I planned to have an item programmed and produced but once I started dealing with the designer it took literally months to ever get in contact with the actual designer after dealing with 3-4 other "middle men". File came back and I printed it out myself . It needed a minor adjustment but I could get no one to respond to my requests. Just crickets. I suggest you spend the money to take a community college 3D design class. It will take far less time to learn to do it yourself and with far less agravation than dealing with Shapeways to get their customer service act together. There is a reason almost all reviews are 1star reviews. Too bad there is not a Zero star review
