Any thoughts on how to design a printable Follow Focus system that can be adjusted, but doesn’t interfere with the Follow focus knob? Ideas are more than welcome!

Still working on the Follow focus system for the DSLRigger. Having issues finding a good solution that is easy to print which solves the problem where you need to adjust the follow focus according to lens diameter.

In this version, the green part (which holds white and purple) can slide on blue part. The blue part is attached to the main system. Adjusting the green part outwards will enable larger lenses, and/or changing angle of the follow focus knob so it’s not always straight out from the lens.

Tips are more than welcome!
