I've recently added these products:
We create scale model components for aircraft and spacecraft
As an avid scale modeller, I found that for my scratchbuild projects I occasionally needed parts that are not available commercially, and would be difficult to create from scratch. I started creating these parts using the Shapeways 3D printing service, and now I'm making these parts available to others.
This website lists the parts I've designed, and contains additional information on building a model using these parts.
