I uploaded a project I'm working on and have some questions about it. The object itself is hollow, it's a case for a device I'm working on. However I think the Shapeways system seems to think it's a solid object and the price is like $1400 for a 9"x9"x3.25" hollow object. Am I missing something here? http://www.shapeways.com/model/128033/case_take_1.html I was kinda expecting it to cost less as 938cm3 is a little much. Any ideas?
