Anet A6 - extruder 50mm fan duct
thingiverse
This is my first model made in F360 so be understanding :] I decided to replace stock 40mm extruder fan which is loud as hell! Cause all 40mm low-rpm fans have lower efficiency than Anet fan I chose the 50x15 fan. In my case it is extremely quiet Sunon HA50151V4-000U-999 (12V, 17dB, 3500RPM). This duct is compatilble with musta's Anet Tabbed Magnetic Extruder Fan Access remix https://www.thingiverse.com/thing:2753133 ... and is designed for round 4x2 magnets too. REMARKS: Due to inconsistent printers tolerances sockets for magnets and pins may need drill a little bit (pins - 3mm, magnets - 4mm). Duct has been installed in my printer week ago and difference is HUUUUGE! New fan is almost inaudible from more than 1m. Now the blower fan drives me crazy xD BTW. This mod increase car weight only by 20g. EDIT 2018/01/10: I've uploaded the final version of fan duct (Anet a6_fan_50_duct_V4.stl) - it's suitable for stock X-carriage EDIT 2018/05/19: I've uploaded the straight version of fan duct (Anet a6_fan_50_duct_straight_V2.stl) - it's suitable for custom X-carriage like https://www.thingiverse.com/thing:2106854
