prusa fan duct redirect

thingiverse

The stock duct started to hang after a bad print had pushed on it, making the hole the screw threads into not so tight, and it started dragging . I'm not sure how good the stock one actually performed, but this seems to be directing good airflow. This should wedge into the fan hole just fine and hold, but I would consider adding some adhesive, especially since it vibrates if you just wedge it in.
