I finally released the CAD files for the FAN segment I was working on for a long time. I prepared two segments. One can hold a standard 120mm axial fan (the one of a kind that probably sits in your PC housing next to you). The other one can hold a 120mm radial Fan. This can be helpful if you need not only airflow but also some more pressure. (For example if you plan to use some filter system in your PrintAirPipe System. :))

The Cad files are available here:

• Radial Fan Segment: https://nerdiy.de/en/product-2/printairpipe-120mm-radial-luefter-segment-3d-druckbar-stl-dateien/

Enough words, here are pictures and videos. :)

PCB used in both segments to control the Fan and read RPM data:

At this point I want to send a huge Thank You to the guys of PCBWay.com again. They supported me at the design of the Fan driver PCB. :)
