This is My Documentation on the Dual-Extrusion Upgrade for the Ender 3! https://docs.google.com/document/d/1IQDRLj9uF0QOfPY6kHdVu1ddVpu4g-P312D2ZuL-EcA/edit?usp=sharing With this mount, you can reach all four screws (two per side) that hold the separate hotends in place to adjust the height difference between them. I despise supports so I designed this upgrade to be printable without any. Although it is recommended to use at least one support on the carriage for the hole of the front fan. The SpacerFanDuct has to be printed twice if you need it. It offsets both fanducts 5mm upwards if your hotends are shorter than mine, preventing them from reaching too far below and making it impossible to get your nozzle on the bed. You can manipulate these spacers as needed depending on how much your fanducts need to be offset. Since this model touches the radiator itself, I recommend printing it in ABS/PETG or something similar for better heat resistance. However, I designed it so that it only touches at the very top where everything should be cool to the touch and has 5mm clearance on all hot parts. If printed in PLA, I would suggest more walls and infill. Offset values: X -59.3 and Y 6.7
