This is a refillable alternative to the original activated carbon filter by Bambu Lab. Just fill the box with activated carbon (I bought mine here: https://amzn.to/3lYflF9), and you are ready for another 60 days of printing. As shown in the video below, please make sure you add some tape to the lid to remove the box easily. I recommend printing this in PETG, ASA, or ABS, as the heat might be too high for PLA. You don't need any support.
