Triple fan duct (2x40 + 1x30)

thingiverse

A custom triple fan duct designed to accommodate two 40mm fans and one 30mm fan is utilized in conjunction with an MK8 hotend. **Update:** A revised version of the design, known as V2 remix, has been created to enhance airflow. **Revision:** The Version 3 redesign addresses all issues encountered in V1 and V2. This duct is currently being used on a U30 printer equipped with the original 30x30 fan, alongside two Sunon MF40202VX-1000U-A99 fans. **Airflow results are dependent upon fan specifications**, so users with different fan models may experience varying airflow rates. The design has proven functional despite some room for improvement, as seen in the "water test" image. Future enhancements to the duct are planned. Two optional components are included: * A wedge, which is recommended for use and can be printed using a flexible filament for optimal results. * A ledbar support, specifically designed to accommodate a salvaged 5v LED bar from a broken flashlight. A silicon socket is also employed on the nozzle, although its necessity remains uncertain.
