Description

https://www.thingiverse.com/thing:4897631 Update: Ahmad has created a version 2 of his design - please go check it out and donate to him: https://grabcad.com/library/mbot3d-mk2_rev2-0-ender7-style-fan-duct-1 Important: This is a remix of https://grabcad.com/library/mbot3d-extruder-mk-2-mod-1 by Ahmad Sunardi I think this is the most beautiful fan duct for the Ender 3 V2 increasing the cooling performance by using two 4010 blower fans. However the original design of the above creator had some issues which I fixed in this remix. Mainly the hole on the front for the heat break cooler - it is simply too small so that the heat break was not cooled sufficiently. Also I added a tab to reduce air leaking onto the part. The design consists of three parts: - Frontplate_V3.stl - the main body - Backplate_V3.stl - used to mount the main body to the carriage - Airducts_V3.stl - holds the two fans Alternative for a 4020 Sunon fan: - Frontplate_Sunon4020.stl - the main body - Airducts_Sunon4020.stl - the airducts This air duct has some neat features: - dual 4010 fans with part cooling from both sides - the main body is hinged and can be removed with only two screws - the blower fans sit in a seperate housing - BL Touch works with the stock metal bracket I would not recommend to print this in PLA as it sits quite close to the hotend. I used PETG and GreenTec - both work perfectly fine. Update: I have added a version for a 4020 Sunon fan as the heatsink fan. The respective files are named *_Sunon4020.stl.
