Creality Ender 5 Plus Ring fan duct.
To blow air around the 3D printed part.
Uses two blower fans for the part and a hot end fan.
I do not know if the is any better than the Original Creality Ender 5 Plus fan that only blows part air from the right hand side.
This unit moves the Hot End forward, This is sorted by changing the 2 x top back brackets for aluminum corner brackets and moving the Y carriage switch.
