Anycubic i3 Mega Stepper Driver Duct

Duct to direct airflow over stepper drivers in Anycubic I3 Mega and out the side of the base. Internal duct clearance is large enough for aftermarket stepper drivers with taller heatsinks. Relocates stock stepper driver fan (you may have to reroute the fan wires from under to board to over the board) and discards original fan mount.
