Ender 4 Magnetic 5015 Fan Duct

thingiverse

I designed the original duct as is, to preserve the original printhead-housing. My goal was to attach the laser magnetically whenever needed. So, the idea emerged to attach the duct magnetically as well. Next, I aimed to improve airflow through my duct. To achieve this, I remixed it here for a 5015 fan. Radial fans perform better in this regard. Print the modified duct upside down since it includes an added support that touches the buildplate. In addition, you will need: A 5015 fan, preferably running on 24 V power Two neodymium magnets with a diameter of 10 mm and a thickness of 3 mm One 3x20mm screw and nut for securing the fan A plug connector compatible with either 12V or 24 V (e.g., a 2-wire JST battery-plug) Wire with a connector, which can be mounted on the fan, connected to the controller board Note that depending on your specific fan model, you may use either the 24 V power from the Ender-4 Board (which some models utilize for LEDs) or the 12 V power located under the plug labeled "laser". This latter option is controlled by Marlin (version 2.0).
