I think that my previous post ( http://www.shapeways.com/forum/index.php?t=msg&&th=6 465&goto=35087#msg_35087) may have been in the wrong thread, so I'm starting a new one to deal with the issue. It appears that changing a model to a co-creator changes the price of some of the materials. I have confirmed this by changing another model of mine from normal to co-creator and back. The prices were as expected when the model was normal and were inflated when co-creator. I have not been able to derive a relationship which would indicate how the prices are being modified. The increase does not appear to be a percentage or static value. The main oddity I see is that the co-creator prices are generally rounded to the a 5-cent boundary. As an additional example (beyond what is posted in that other thread), the model I switched tonight went from ~$303 for stainless steel to $350. The heart ornament (my previous discovery) went from $40 to $50. 1. Is this behavior intentional? 1.a. If the behavior is intentional, is it documented anywhere? 1.a.1. If the behavior is not documented anywhere, why not? I have been generally pleased with Shapeways' communications - let's keep things like this in the open. 1.a.2 If the behavior is documented somewhere, where is it? 1.b. If the behavior is not intentional, when will it be corrected?
