I can make them available unpolished too yeah, but the joint tolerances have been tested for the polished material - so for unpolished I can't quite guarantee joint fit. Shapeways states the polishing process can take off a tenth of a mm on average. I can imagine an unpolished version might have really tight fit for some of the joints ( although I can imagine that can be fixed with some sanding ). Btw, Shapeways will soon update their polishing process for improved smoothness but better detail retention. Anyway, I'll make it available in white & black unpolished for you.
