Ok...minor bump with Sculteo. They treat Alumide differently than the other Plastic materials. Apparently, you cant group parts together for Alumide. It makes no
sense, but they make the rules. Fortunately, their pricing on Alumide is much better than Shapeways, so if anyone wants an Alumide version, they will need to get the parts separately.
I uploaded the separate part models for the v3.1, however, you loose some of the discount for the the multi part models, (buttons and rings get hit hard) but alumide overall ordered in separate parts is still way cheaper than Shapeways

I also put up a looped and sprued model specifically for Alumide on the Full Internal Assembly. I would consider it a Beta unit, because Sculpteo may not allow that either. Not many people really get Alumide for internals, but I thought I would uploaded it anyway just incase some one wants to try it out.
Still working on separate parts for the mechanical.....
