I was looking for some detail parts, mainly furniture and interior details at a reasonable price, and was having trouble finding any, so I decided to teach myself about 3d printing. What you see are the results (so far). I am still learning! Let me know if you have a particular request.

I started a Blog where I talked about my 3D design process to produce models on Shapeways. Although I haven't updated it lately it's a good basic explanation.
