Fisher Fan Duct for ABS

thingiverse

This is a cutting-edge prototype and untested replacement fan duct designed specifically for use with ABS on the RepRap Fisher. It prevents the part from being blown away while allowing air to escape sideways from the cooling of the hot end, thereby avoiding the part entirely. Requiring minimal effort to swap out, the Fisher extruder utilizes just one bolt to secure this in place. When using this untested design, you do so at your own risk. To enhance performance, the fan duct could be optimized by reducing its profile, allowing for a more streamlined design that minimizes unnecessary ductwork. For now, I have sealed the duct ends to prevent air leaks.
