I uploaded a model and saw the pricing for its current size in stainless steel was around 80 dollars, and I thought, okay, that's cool, so I slightly increased the models size, hoping to get it a little big bigger and printed in steel to catch the detail, and it went from being around 80 dollars, to over 720. Why did it jump the price like crazy when I barely increased the size? I thought it would bump up to around 100 dollars, but definitely not that much. Any input on this would be helpful. Thanks.
