Hi!
I bought a print chamber heater on AliExpress, designed for another printer brand, but it also fits the Flashforge Adventurer 5M without any problems. The heater works in the printer without any problems and does its job! I designed a mount for it so that it does not stand loosely and does not interfere with the moving parts of the printer. Even when the printer is working hard, the heater barely moves.
Mount designed for screws from kit with chamber. Print with PLA, but PETG/ABS would be better. I will add the lower mount soon, I'm still working on it.
