*****I didn't realize they now have stainless steel. I'll have to order their material sample kit and give it a try.
I see they have tutorials for using various modeling programs, but not MoI. Any pointers on making a MoI file for Shapeway?******

Hello Ed,

I recently uploaded a .STL file to Shapeways – that's the standard for prototyping I guess. On their site, they recommend pulling the .STL through Meshlab or Netfabb (Programs to do certain checks and repairs on vertices and normals) before you upload. I got some warnings from a MoI .STL file in Netfabb, but those were not critical. I'll also post the results, when printed.

btw: the sample kit is really worth the money – you just get a better feeling for the materials, you're designing for.

Greetings,
Sebastian
