(Yes, these things cost an arm and a leg in shops.)
all gears have the same outer but different inner diameters.
(You you need not adjust your follow focus when switching lenses.)
All gears have their nominal inner diameter labeled onto them in 3d letters.
60mm = 56-60mm
62mm = 59-62mm
65mm = 62-65mm
68mm = 64-70mm
70mm = 67-70mm
example lens-sizes for a few DSLR lenses:
Name ....................... lens gear size (filter size)
Panasonic 14-42 ............ 60mm
Canon FD 50mm f1.2 (nicht L) 62mm (52mm)
Canon FD 50mm f1.2L ........ 65mm (55mm)

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.
