Filament dust filter for Anycubic i3 mega. attaches where the Bowden extruder sits (need to remove!! Filament sensor completely from that position.)
(I have my filament sensor tucked away inside with a piece of filament in it. (don't really need it)
attaches bottom piece with 3 small M3 screws.
"This allows you to print with old crappy Filament" like in my case with the role of black pla that came with the printer.
JP Pla (better ABS)
doesnt matter, just do 3 outer layers and it should be strong enough
