Air Purifier - Portable - Quick and Easy Print

I wanted a simple Corsi-Rosenthal type air purifier I could break down and carry in a three-day bag.  The main limitation was the Mk3 print bed, so for me it needed to use 6" filters.  I had some 120mm case fans lying around, bought a fan controller and we were good to go.

The parts do need to be mirrored, so be sure to print both Side A and Side B.  I used a 0.6mm extrusion width (0.4mm nozzle) for the perimeters for added strength and a faster print, but this is not necessary.  For assembly, I used the self tapping screws that came with the fans, although the mounting holes are sized for 4mm screws if you need other options.  If needed, rubber bands may be used to secure the two sides to one another.

If you have specific filter dimensions (best to take actual measurements of the filters in-hand) I can make custom sizes.
