This collective base uses the one shown by Element 14 as a starting point with a few modifications made to it.
A linear potentiometer is being used instead of a 128 position absolute encoder to give finer control and steps for the position of the collective.
A sleeve is used to reduce the diameter as I will be using a small aluminum pipe in my build
A new base plate was used because
There was no base plate in their archive
No holes to mount to a rig / chair
No holes to mount Arduino board
No hole for connector to make it quick to remove the handle

This was designed in FreeCAD specific to my layout so that I could bolt the collective to my chair as well as bolt the various electronics that I have directly to the plate.
The base plate that Element14 uses was not included in their STL package and was laser cut from Acrylic IIRC. Mine was 3D printed out of PLA.
