P1S exhaust to Xiaomi Air Purifier 2S

I connected an exhaust duct from the printer to my home air purifier

Two printed parts: 3D printer back panel connector and air purifier side panel connector

The 3D printer back panel connector is held to the back panel by 8 10x5mm cylindrical magnets. I left small holes for each magnet position for future removal of the magnets

The PP steel wire spiral exhaust duct can be screwed directly onto the connector counter-clockwise [Please note the thread direction of the ventilation pipe you purchased!!! I am not sure if all ventilation pipes have the same thread direction]

Attach the connector with magnets to the printer's back panel. The connector may slide down due to gravity, so you can insert two M2.5x10 screws into the upper and lower holes on the printer's back panel to secure the connector (these two holes don't seem to have threads, so the screws are just inserted. If you find screws of appropriate size that can be threaded into these two holes, please let me know in the comments)

I chose this type of spiral ventilation pipe, with an inner diameter of 40mm and an outer diameter of 50mm

The other end of the ventilation pipe screws into the purifier end connector

Fix the connector to the purifier side panel using 4 M2.5x10 screws + 4 M2.5 nuts (washers may be needed on the inside of the purifier). If you find the holes don't align, try rotating it 90 degrees.

Then place the printer and purifier in your desired positions and straighten the ventilation pipe.
