cyclon filter / pre-seperator

inspired by [this youtube video](https://www.youtube.com/watch?v=50UtHTSGE24) we decided to make our own cyclone pre-seperator custom to our vacuum cleaner. Description and fotos can be found on [our website](https://konstruktiv-berlin.de/2023/09/18/zyklon-abscheider/) (sorry, german only).

The design works very well, especially for milling chips in the workshop - which was the main reason we build it.

The parts have been printed on a Prusa MKS3+ and fit in the print volume nicely.
