Front of Skull Model

Additional Information: I have been submitting this part to all the 3D printing places online as a comparison so I can decide which service I want to use once my project is finished prototyping, and is ready for public sale. Although I want to produce 1 for now, I am interested in bulk pricing and volume discounts for when I am ready to produce these for sale. By getting quotes for the exact same part from all the 3D printing places I can find, I can narrow it down to those places that charge a price that makes it possible for me to sell the product at a price people are willing to pay. I would appreciate a quote for a single piece, and also bulk orders if you offer better pricing for quantity. If you offer a variety of materials, perhaps you could quote me prices for them all, or contact me with a list, and I will select them. I want the lowest price I can get that still has reasonable resolution and quality. Thank you. Bob
