That was very kind of you Mario - thanks. Your mention of refining a design to minimize the volume of 3D printed material is a perspective I hadn't really thought about. In the past I've worked with friends and casters to produce a handful of special lost wax brass part for locomotive detailing projects (e.g. a correctly shaped PRR K4s sand dome). With that medium labor tends to be the the factor driving production cost. Does Shapeways offer anything in the way of volume discounts if one needed dozens of the same part?
One of the things I like about the OGR forum is that it provides have a place where scale oriented modelers actually building and running 2 and 3 rail equipment can meet and exchange ideas and interests
