Description
This is a very simple follow-focus using a roller-blade or skateboard -wheel instead of gears.
It's great to experiment with a follow focus on a shoulder-rig without investing a lot of time and effort into a more complex geared or even remote follow focus.
See thingiverse.com/thing:7256 for a much cooler but also more complex design requiring electronics and microcontroller-programming.
Update:
I added a (not yet tested) straight version of this follow focus because with my new matte box there was not enough space to mount this anymore.

Instructions
I CHALLENGE YOU TO DESIGN A GEARED FOLLOW FOCUS!
Assembly is trivial.
I don't really need to write anything about that here. ;)

More from MarcusWolschon
Added a straight version for short lenses that does not get in the way of a matte box or other large things in front of the lens.
I found the straight version to need more room to adjust it's location.
V1 turned out to work fine with the skateboard-wheel but I needed it longer for the inline-skate-wheel.
So here is version 2.
Why not separate into two pieces and make the angle adjustable?
