How can you have an article about downloadable physical objects without mentioning Shapeways? http://www.shapeways.com/model/227707/ The uploader chooses the materials the object is available in (Shapeways will print it in that material and send it to you), or whether you can download the file and print it yourself. http://www.shapeways.com/model/449442/the_piratebay_ship.htm...
