Calculation is off?

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? https://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?

Mmmm...Houston we might have a problem. Could you email your file to service@ so they can take a look at it.

Email is sent, haven't heard back yet.

Does it have a hole in it? If not, the new uploader prices it like a solid object. Just a guess ...

It's got 4 holes in fact. I'm guessing it's pricing it like a solid.

That could be what it is.
