I need to increase the thickness of my spiral turbine model and make it hollow while keeping some support segments inside. the same model is needed in the largest scale available at shapeways. Need to add the words "Patent pending" and the patent number in small letters somewhere on the design Please provide your best quote. I pay through paypal when work is complete. the model is the only one available for download at my shop to view what I'm talking about. https://www.shapeways.com/shops/GoldenSpiralTurbine thank you
