prusa fan duct redirect

thingiverse

The original duct began to sag after a faulty print forced its way onto it, causing the screw threads' hole to lose its tight grip and drag on everything . I'm unsure about the stock one's performance, but this modification appears to be directing airflow effectively. The new piece should fit snugly into the fan hole and hold securely, although adding some adhesive might be a good idea, especially since it vibrates if simply wedged in place.
