Only the price for WSF and BSF is different, so it's probably this:
https://www.shapeways.com/blog/archives/490-Significant-price -reduction-on-dense-models.html
@SHAPEWAYS: I can't easily find a link to that page. At least not on the WSF material or pricing page?
I think the first one has a volume that is 100% of it's bounding box.
So it's eligible for the discount for models with density above 10%.
The second one is diagonal making the bounding box larger compared to the model itself, reaching below 10% density I guess..
Cheers
