Seamless Lens Focus Gear Generator

Hello even more creative DIY Cine / Movie Making Amateurs and Professionals, This was a Long Lost Generator.
Gladly some people make backups and modify it so it can be used more easily.

Install OpenSCAD from https://www.openscad.org/ 
Open the *.SCAD File in OpenSCAD and look on the left menu with all the Code in it.
PLEASE READ THE README FILE!

I have printed a couple of gears with just PLA but that will become more brittle over time.
My Focus Gears are still working but I recommend using ABS. Don't like the ABS Smell? You could use some FormFutura ClearScent ABS (It does not smell like ABS).

If you want to go overboard go use FormFutura's Titan-X, It doesnt warp and sticks really really well to your build Platform!

If your Printer is not able to print those materials... Well... My Favorite Material is FormFutura's Volcano PLA. This is an amazing PLA and it's super strong and is used in the Rapid Prototyping Engineering Industry a lot!

Oh and TPU is also a great material for this kind of application, just be sure the diameter is a bit smaller so it perfectly grips the TPU to the lens barrel.
