    I have a design in mind which is simple enough that I can define it by generating a text STL file. AFAIK there's just one detail missing. What is the implicit unit of length for all the vertex values? Thanks.

    There is no unit of length defined in an STL file. This is one of the problems with STL. When you upload to Shapeways, you can choose the unit.
