Full height long duct is 65mm (length of "standard" duct v.1.0 is 55mm)
The source file was taken as "Duct v.1.0" for Autodesk Inventor, attached by the author to the printer project.
File for Autodesk Inventor with my version duct attached. The my part scales correctly; if you know how to use Autodesk Inventor, then you can easily and freely change the length of the part.
In one of the photos the inductive sensor holder is visible (black detail). This holder is described in a separate thing, HyperCube Evolution: Holder for the inductive sensor.
