We would love to have more tutorials up. So, are you an expert with a particular 3D modeling tool and would you like to help the Shapeways community and the people that use the same tool as you do? We're very interested in tutorials that help people convert files to Shapeways. Email me! joris (at) shapeways (dot) com Tutorials on how to design for 3D printing or with tips such as how to invert normals are awesome too. We will credit your work on the tutorial as well as place a shrine in your image at the Shapeways offices.
