Just print 3 parts Bottom tray, Main Hat for 4010(same as original size) for Active Carbon Pellet, Adapter for 4020 fan. In case you want to use external power you can use screw wholes at top of the back place, if you do not want to open the back panel you can just hold the cable with zip tie using these wholes and zip tie to original cable going into back panels(My picture shows the case of DO NOT OPEN backpanel, just use wholes and exising cable and tape 2 points). BOM Anycubic AirPure Acid Free Active Carbon Pellet Optional Surgical Mask Optional 4020 fan ← replace original fan Optional USB Cable for Bus power operation for long print. Small air purifier for 3D Printer? For both FDM and SLA printer smell sometimes and concering about VOC pollution. ABS? Resin?,,,,, then people buy small air purifier which has active carbon filter inside. Elegoo? Anycubic and SUNLU?….whichever you can buy it costs about 20-30USD / 1pair…. Build Bento Box?….Bento Mini???????,,,,,not so effective choice. Area to improve for those products whichever you buy → Solution with Anycubic Airpure Too weak air flow → Change 4020 Noctua or any faster RPM fan with strong air flow No pre or post filter → You can put surgical mask inside original hat No replacement of Active carbon filter → just use acid free active carbon pellet Where to Buy Your Consumables ( links below are not affiliated unless stated) - Thanks thrutheframe @thrutheframe Acid-free activated carbon: US - Voxelpla offers acid-free activated carbon in a 1lb pack and HEPA filter replacement.
