Anet A6 - extruder 50mm fan duct

thingiverse

This is my first model created in Fusion 360, so be patient with me :]\r\n\r\nI chose to replace the stock 40mm extruder fan, which is extremely loud! All 40mm low-rpm fans have lower efficiency than the Anet fan I selected. I decided on a 50x15 fan.\r\n\r\nIn my case, the Sunon HA50151V4-000U-999 (12V, 17dB, 3500RPM) is extremely quiet.\r\n\r\nThis duct is compatible with most Anet Tabbed Magnetic Extruder Fan Access remixes,\r\nhttps://www.thingiverse.com/thing:2753133\r\n\r\n... and it's designed for round 4x2 magnets too.\r\n\r\nREMINDER:\r\nDue to inconsistent printer tolerances, sockets for magnets and pins may need a little drilling (pins - 3mm, magnets - 4mm).\r\n\r\nThe duct has been installed in my printer for a week now, and the difference is HUGE! The new fan is almost inaudible from more than 1m. Now the blower fan drives me crazy xD \r\n\r\nBy the way, this mod increases the car's weight by only 20g.\r\n\r\nEDIT 2018/01/10:\r\nI've uploaded the final version of the fan duct (Anet a6_fan_50_duct_V4.stl) - it's suitable for stock X-carriage\r\n\r\nEDIT 2018/05/19:\r\nI've uploaded the straight version of the fan duct (Anet a6_fan_50_duct_straight_V2.stl) - it's suitable for custom X-carriage like https://www.thingiverse.com/thing:2106854
