40 mm fan holder to duct fan for A8 i3 bowden or direct drive

thingiverse

This adapter for a 40 mm fan lets you replace the sometimes loud vertical circular fan on an A8 Anet or I3 Prusa with a 40mm flat fan. This modification also allows you to use any design of duct fan directly with a 40 mm fan plate. It has been re-designed to include a gutter for a removable door holder, for those who have printed the fan modification for the extruder. The modifications in this mod are only done using the parts provided as an addition to the A8. This mod is compatible with direct drive or Bowden! The spacer (the washer), should be printed if you don't use the door holder so that it solidifies the fixation. Thanks to Quentin Corda, who participated in this project by designing a similar piece. *****Update from February 26th, some people reported that the fan moved if not correctly clipped on the tube. This new version can solve this issue. Try both and report to me thanks***** If you have the modification or want to do the modification for the extruder fan, you will need: The fan spacer: https://www.thingiverse.com/thing:1798669 The A8 extruder mod, you only need to print the door that goes to the extruder, not the part of the vertical fan: https://www.thingiverse.com/thing:2290361 The semi-circular duct fan: https://www.thingiverse.com/thing:1954001 Spriya duct fan: https://www.thingiverse.com/thing:2133328 Spaceship: https://www.thingiverse.com/thing:2088006 Circular: https://www.thingiverse.com/thing:2037771
