This is Active carbon filter hat for Anycubic AirPure fits for not just 4010 original fan configuration but also 4020 mod.
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).
