Lọc gió carbon phía sau cho K1 Max

I was not able to find a good K1 Max rear carbon filter so I designed one of my own. This can be slipped into the back of the printer without magnets or screws. You can cut your own carbon filter to the right size from a larger and less expensive sheet. I was able to cut it to a 100mm strip and fold it over 4 times to get a better filtering effect.
