Camera Lens Follow Focus / Zoom Finger Lever (2 Leverage Position)

Can't find what I need for my purpose that suits my style so I made one.

There are 2 finger slots, inner for faster rotation and outer for more control.

Things Needed - 1 small zip tie (or M5 screw and nut)

Fits lens girth from - 77.5 - 81.5 mm

Finger hole diameter - 16.5 (outer ring) & 13.5 x 23 oblong (inner ring) mm.

Can be scaled up-to + or - 10%
You can do the simple math to fit your lens =)

You're welcome to mix this, have thought of putting self locking ring & extendabl
