I made a model on shapeways and it said it would cost me $58 for the first version I uploaded. Then I realized I made an idiotic mistake and didn't make any mechanism. Oops. I update the model and the price goes up $23 even though the volume went down. Does anybody know what happened?

EDIT: Problem has been solved. The density must be above 10% for discount price.

Your first model had a density of 10.52% which is above their 50% price reduction cuttoff at 10%.

Model 1:
? (20 * 1.40) + ((60.9121 - 20) * (1.40 / 2)) + 1.50
% = 58.13847

Model 2:
? (57.414 * 1.40) + 1.50
% = 81.8796

See https://www.shapeways.com/materials/strong-and-flexible-plastic and then scroll down to the "Density Discount" section.

We also offer a volume and density discount on Strong & Flexible materials. For models that have greater than 10% density (material volume divided by bounding box volume), volume above the first 20cm3 is calculated with a 50% discount.

Yep, you need to arrange the pieces more carefully to get the density back about 10%. Why not use the TomZ PartStacker program if you are having difficulty?

I already fixed it. I just needed to move a few parts like 2mm to do it.
