Revised clamp ring

I downloaded the file "DOC Simple 4x6", I opened it and I noticed that the clamp ring closing device is clearly deformed in the sense of the length of the duct as you can see from the attached images. I find that the deformation along the longitudinal axis has a value of: 1.706510527. Applying a rescaling along this axis, the ellipses become circles again. I was unable to rescaling four complex parts (the gear wheels in red) so I left them as they were. Then I upload the correct file for those who want to investigate the device in its entirety. enjoy.
