PB Design - External Carbon/HEPA Filter for original Creality K1 MAX Exhaust Fan

This is an external Carbon/HEPA filter housing for the Creality K1 MAX exhaust fan, based on the idea of BentoBox. It utilizes the original BentoBox CMAG for the carbon pellets. It sits well in place and takes no tools to maintain it.

BOM:

• 4x M3x12

• 4x M3 Voron style heat inserts

• 8x 4x2 magnets

• 2x HEPA Filter (Bento-Box Style = "iLife V5 robot vacuum cleaner" Filter)

Additional note: The whole system sits well enough in place. It can be easily pulled on/off without any tools for maintenance.

Additional note: Be careful when screwing the coupling onto the main body. The corner with the recessed frame must be at the top.

Additional note: For printing the CMag net_infill, please follow the instructions included at original BentoBox design. This part has to be printed 4 times with top- and bottom-layer settings set to "0": 

I printed my housings in PETG. You should at least print the coupling from a more heat-resistant material than PLA.
