The necessity of computer-based preservation and interpretation of traditional folk crafts is validated by decreasing number of masters, fading technologies, and crafts losing economical grounds. We present a long-term project on the development of the mathematical basis, software tools, and technology for desktop or personal fabrication using compact, cheap, and environmental friendly fabrication devices, including so-called "3D printers". The test application areas for the development are traditional crafts from different cultural backgrounds, namely Japanese lacquer ware called "shikki" and Norwegian carvings. Our project includes modeling existing artifacts, Web presentations of the models, automation of the models fabrication, and the experimental manufacturing of new designs and forms.
