Extended high flow fan duct for Anet A8 with autolevel sensor

thingiverse

This is version 2: The distance to the nozzle has been minimized and air flow in direction to the nozzle was significantly reduced. This duct is optimized to maximize airflow while compensating for the additional space between fan and nozzle caused by this auto-level sensor support:http://www.thingiverse.com/thing:1911146 Without this sensor support, the duct may collide with the nozzle. The design remains straightforward and simple, making it easy to print. No supports are required, and overhangs are limited to 45 degrees. The flat area at the bottom serves as a base for printing. A 2.5mm hole is added to cut an M3 thread for a small bolt to keep it in place. The cross-sectional area of this duct is substantially larger than the original stock duct. Due to the high temperatures near the nozzle, it's best printed in ABS.
