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

This is an external Carbon/HEPA filter housing for the Creality K1 exhaust fan, based on the idea of BentoBox. It utilizes the original BentoBox CMAG for the carbon pellets. Its mounted with magnets only, sits well in place and takes no tools to maintain it. BOM: 24x 6x3 magnets 8x 4x2 magnets 2x HEPA Filter (Bento-Box Style = "iLife V5 robot vacuum cleaner" Filter) Carbon Pellets Parts I used: HEPA Filter: https://de.aliexpress.com/item/4001333137700.html?pdp_npi=4%40dis%21EUR%21%E2%82%AC%206%2C27%21%E2%82%AC%206%2C27%21%21%2150.64%2150.64%21%40211b813f17656501277111213eef4e%2110000015723715590%21sh%21AT%21738244749%21X&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2007550574343.4001333137700&gatewayAdapt=glo2deu Additional note: I run more than one K1 and found out, that these printers have been delivered with different sized exhaust fans over time. They are all 60x60, but with different depth. Consider a more powerful 60x60 fan (e.g. 60x60x25) if you feel that your fan is underpowered. Additional note: The coupling sits snug in place. It can only be mounted in one rotated direction. There is a cutout on one side. 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. Many thanks to @ https://www.printables.com/@thrutheframe to share his great design!! Take a look at the photo gallery. The pictures should be self-explanatory. If you like my design, feel free to like, comment or add a make :) Happy printing!
