TAZ 5 Hexagon Left Side Fan Duct

thingiverse

I've been experiencing issues with PLA curling when my overhang was pointing towards the left side of my build plate. Several versions of fan ducts were designed for older models of the TAZ hotends, but none matched the requirements for the new hexagon hotend. To solve this problem, I created a custom fan duct that utilizes a standard 24v 40mm fan and mimics the look of the factory-designed duct on the opposite side. To enhance performance, I positioned the duct's nozzle at a slight angle, reducing air flow towards the hotend tip when activated. As a result, I was able to minimize heat-related problems while operating in high-speed mode. Additionally, this modification enabled smooth operation without any obstacles, even near the glass bed and the corner hold-downs. This custom design securely attaches to the existing left-side attachment bolt, eliminating the need for new components or adjustments. Follow these easy steps to install the fan duct: 1) Print the part using ABS material; supports are unnecessary. 2) Raise your Z-axis by at least 60mm before starting installation. 3) Remove the mounting bolt from the hotend on the left side of your machine. 4) Place the bolt inside the custom-made duct and secure it using the provided allen wrench while maintaining its designed angle. Apply a suitable torque value for optimal performance. 5) Combine the new fan duct's cables with those from your existing cooling fans. 6) Your prints will now benefit from improved air circulation, ideal for PLA projects.
