That's not Solidworks. That's Geomagic/Alibre and the design changes the inner diameter, so the outher one stays consistent. So I can't make a larger one.

Hey I am trying to use this for a Large Telephoto Nikon 200-500 mm lens. It looks like it needs to be much larger like 94.5mm to work. I dont have solidworks to be able to generate a larger file and I think If I just make it larger that will throw off the gearing. Any chance you could help me out?

Love the design.
