I was interested in printing out this venting setup for my K2 so I could move beyond PLA, PETG, TPU printing without concerns about VOC and other air contaminants. I am hoping to do ABS, ASA, Nylon and other higher VOC materials. Right now I have my printer setup in a space where I spend a lot of time. I may eventually relocate. Mounting it required relocating the filament buffer from the back of the K2 to the CFS unit. Took me a touch of research to figure out how to get the tube out of the output side of the buffer so I could switch it with a longer tube (hint use the lever to press the spring loaded side all the way to the limit and press in on the external outlet side which will release the tube from the holder just like the other tube connections). I popped magnets in, did some tests to see if they would all stay press fit by slapping it to the side of my washing machine. Some of the magnets did come out so I glued those in place with super glue. The parts I ordered from Amazon were as follows (not recommending or not recommending any of them, not sure if they were the best, but they got here the next morning so I could assemble things): Filters: https://www.amazon.com/dp/B0782T7L6P Magnets: https://www.amazon.com/dp/B0CCVSDL89 Carbon Pellets: https://www.amazon.com/dp/B0F293JMWG After setting it up I do have some concerns about air flow and I taped a bit of tissue to try and gage the airflow when I manually set the case fan to 100%. I have added photos of no vent attached. The e vent attached with no filters and no carbon container. You can see strong air flow. But when I put t in the HEPA filters, the airflow coming out drops considerably. I tried with just the filters (no carbon) and with the carbon with the seemingly similar results. Airflow seems to be considerably less. I tried a test with the filter on, printing PETG. With the filter on the case temperature was running at 39c. I do have the vents open on my CFS riser setup. Removing the filter resulted in the case temps steadily drop down to 35c. This lower airflow gives me concern. Perhaps I should only put the unit on when dealing with higher VOC filaments? Or perhaps I made a poor filter choice?
