Ender 2 Pro fan duct

• Improved airflow for more efficient cooling.
• Compatible with both 4010 and 4020 fans.
• Offers an unobstructed view of the nozzle for better monitoring.
• A sturdy design ensures reliability during operation.
• Easy printing and assembly process.
• They are crafted with heat-resistant PETG filament for superior performance (avoid PLA).
• No need for support structures; remove loose strands with a knife.
• Assembly requires three M3x6 screws.

Important Note: One of the screws should be inserted from the rear (as shown in the image above). The fan duct is threaded to support this type of mounting. For added stability, you can drill out the hole with a 3 mm bit and utilize a screw and nut.
