Sunhokey Prusa i3 Adjustable Dual Fan Duct

thingiverse

This is a dual Fan duct that directly attaches where the original Fan was mounted. My printer is a Reprap Prusa Sunhokey 2015 model, but I've since upgraded the extruder with a new clone that's slightly shorter than the original. I needed to find a reliable dual fan duct that directs air exactly where it's needed, and this proved to be a challenge. This Bracket and duct assembly is highly adjustable on all three axes. The bracket mounts securely to the frame and can shift along the x-axis. The ducts can be precisely adjusted in both y and z-axes to allow for optimal direction of the airflow. Standard 40mm 12V laptop fans were used, requiring two units wired in parallel. Once installed, I wrapped the fan ducts with foil tape to prevent them from sticking to the extruder if they jam against a warped part.
