Make sure your Normals are properly oriented. the upload is supposed to catch inverted normals but I have seen it fail a few times.
If you need help with normals, let me know.

Ya you do. I can tell from the picture.
I suspect you made a mirror copy, yes?
Are you using Blender?

Hey guys,
got the good results now, but the shapeways price on the website says: 23.87,,, and the old version of virtox i use,, where the old price is $1.68 for WSF, it says my object is $23.58.
i don't want to say i have a diffrence of about 30cents, but that was virtox his old calculator, with the price of $1.68 for the WSF,,,
so the price for the shapeways objects after the new discount (see shapeways newsletter) is not on yet?
cause that would mean the objects should be cheaper?

I have one on the topic of pricing error. The FAQ states that "The price of a model depends on the volume...". I recently uploaded a model of which the price calculation did not seem correct to me, so I uploaded some test models and here are the results:
test1: A 10x10x10 mm cube. Volume is obviously 1 cubic cm. Price is $ 3.57. Lets call this the unit price.
test2: A 10x10x10 mm cube with a 6x6x6 inverted cube inside. The volume is 0.784 cubic cm. (1 - 0.6 x 0.6 x 0.6.) The price is 89.1% of the unit price. Do note that I did not put holes in the sides, so the excess material would be trapped and shipped.
test3: Here it really comes. This model resembles my model more and has all room to let excess material out. A 10x10x10 mm cube consisting only of its ribs in 2 mm. The volume is 0.352 cubic cm. (8 x 0.2 x 0.2 x 0.2 + 12 x 0.2 x 0.2 x 0.6.) The price however still sticks at 67.8% of the unit price. (The model is one manifold volume, no overlaps.)

There is now also a fixed price of $1.50 added to the price of each piece. You need to subtract it from the given price to get your unit (per volume) price. I have found pretty good accuracy of price = 1.50 + 1.50*Volume in CC.

Thanks, that solves it. Not directly with $ 1.50. But it does after I add 19% tax to that $ 1.50. So, big is the way to go
