Prusa Fan Ducts
by DR2D, published
This is the input and output ducts for a Prusa extruder fan.
This design is based on the design from ncbob. â€œDuct for 40mm Fan for Greg's X-Carriageâ€. The fan I installed had vanes that spilled air down onto the print bed and affected print adhesion. The duct to the extruder has been shortened and angled up. An input fan shroud has been added (that clears the z-axes lead screw) to draws air in from the top.
