A 3D printable ventilation pipe system with all kind of different connectors and pipe segments.

Similar projects worth following

The PrintAirPipe System is a 3D printable pipe system. Using the different pipe segments, an individual and customizable exhaust or supply air system can be set up. Ideal for conveying the exhaust air from a soldering station, 3D printer or similar to a suitable filter system or wall outlet.

The PrintAirPipe system consists of different segments that can be individually connected to each other.

There are currently the following segments available:

  • Flange segment
  • Butterfly valve segment
  • 120mm fan insert
  • Filter segment
  • Adapter to 100mm PrintAirPipe standard
  • Adapter to 80mm PrintAirPipe standard
  • Adapter to 50mm PrintAirPipe standard
  • 90° connector
  • 45° connector
  • 22.5° connector
  • Y-distributor segment
  • Y-distributor straight segment
  • Extension 50mm
  • Extension 100mm
  • Extension 150mm
  • Extension 200mm
  • Cover cap
  • and more...

Wow! This is a great system!

I see that there is a fan segment called out in the overview picture, but I don’t see it in the list of STLs. Is that a planned item?

  Are you sure? yes | no

Thank you. :)

There was a typo in the list at the top. (I wrote "20mm fan insert" instead of "120mm fan insert"). Anyways, the segment is included.

Currently I'm also working on a radial and axial fan segment that can be powered directly via USB-C. I introduced the PCB recently here:

Hope you like it. :)
