Vacuum Cleaner Nozzle

I needed a nozzle for an old AEG Vampyr 6006 model which seems to have some unusal connection not found somewhere else.

So I decided to design a new one.

The parameters of this model can be easily adapted in a FreeCAD spreadsheet. So in future I will be able to quickly design a new one for other machines.

The STL file shows a model having an 18x6mm intake with a shaft compatible to AEG Vampyr 6006.
