Hallo, I am not sure I understand the pricing. I have uploaded a model of a small lampshade. Volume is 34ccm (bounding box 11x11x12cm), which should make $48 in White Strong & Flexible. Instead the Online-Calculator says EUR 116 ($153). Is something wrong with my model? I made it in SketchUp, converted to stl with Meshup and "healed" it with Netfabb (some red areas left). Best regards d.
