My remix of mgx's variant of the cyclone dust scrubber, adding the possibility to define different sizes for the inlet and outlet. I also added a thread for the standard european PET water bottles (thread from Necks & Caps Library by Xavan, thing:1654620).
The provided stl was made with a 32mm OD vacuum hose connector and 19mm ID inlet towards the dust shoe.
Just add swiss spring water bottle :-)

EDIT: After a few weeks of testing with aluminum, it works fine so far. The bottle I'm using compresses a bit from the vacuum but still does the job.
