Contraptor is a DIY open source construction set for experimental personal fabrication, desktop manufacturing, prototyping and bootstrapping. Various Ñartesian robots can be assembled from Contraptor and used as a prototyping platform for projects such as XY plotter, mini CNC machine, 3D printer etc. You can make components of the Structural + Basic linear motion subsets of Contraptor at home for about $300 in parts and materials, plus shipping, taxes and time. Sketchup models of Contraptor components are hosted on Google 3D Warehouse while the DXF exports and SVG templates are hosted on Thingiverse, a cool new site for sharing hardware designs. If you like the set but don’t want to make it, we’re working with Hines Design Labs to fabricate a small quantity of Contraptor subsets, and then release the design/manufacturing files under an open source license, so that anyone with Shopbot could do the same. The initial kits are planned to be sold at or below cost – $150 to 250 depending on the subset. We need 10 committed buyers for Structural subset kit ($200) and 10 for Basic linear motion subset kit ($250).
