Summary

A simple air purifier made with computer fans and HEPA filter paper. Key being you only need to replace the HEPA paper itself when the filter gets dirty, which is times cheaper than replacing the entire filter unit. See "README-assembly instruction.docx" for bill of materials and other instructions.

Key points:

Both double and single fan versions:
- are adaptable to HEPA paper of all width and a wide range of folded height
- requires replacing HEPA paper itself ONLY when replacing the filter
Double fan version:
- helps with stacking up power of computer fans
- can be glued to the wall, in addition to standing on the ground
Single fan version:
- is for those with beefy fans
- is cheaper to print and easier to install than the double fan version
- can stand on the ground only

Print Settings

Printer:
Bluemaker M350
Rafts:
No
Supports:
No
Resolution:
0.2mm
Infill:
15%
Filament brand:
SUNLU
Filament color:
very fancy three-color quantum
Filament material:
PLA+
Notes:
Mostly no raft no support except the fan case does require support. The mesh may require a raft if your bed adhesion is not so good. Normal PLA would work for this. You can download the 3mf files for a read-to-go setup in Prusaslicer. If you want to set up yourself, please refer to the pictures for what to print.

Note if you go for the double fan 3mf file, you need to print everything on the bed TWICE.

The stl files are everything-combined and needs to be split into objects in your slicer.
