(EN) Printing a gearless follow focus
The prototype of my shoulder rig worked fine so far.
Improvements to the T-connectors are possible but it works.
Now, inspired by this DIY Gearless Follow Focus on DVXUsers, I'm printing my own improvised follow focus for this rig.
The follow focus works but the skateboard-wheel I tried first has little grip.
So I replaced it with a larger inline-skate wheel. That works much better.
+ softer wheel has better grip
- larger wheel means gear-ratio of about 1:1 instead if 3:1
- heavier wheel means printing the follow-focus again with 60% instead of 20% infill for added mechanical strength
I've posted the design on thingiverse for others to print and improve.
You can see all photos in my picasa album.
I also added a
* counter weight this same weekend
Update 3: The printed parts are also available on shapeways. (If you can't get access to a 3d printer yourself)
