ADKS - Ender 3 Pro/St Fan Duct

Hi All, Here is my design for an alternative fan duct for Ender 3 Standard/Pro 3D Printers. In an attempt to quiet my Ender 3 Pro, I designed this hotend fan duct to use 4010 or 4020 cooling fans and obtain a single-piece object easy to print without the need for particular support during the printing phase. In my case, I installed a Sunon MF40202V2 24V fan for the hotend and the stock 4010 fan from the motherboard case as part cooling fan.

Additional information:

- Two separate ducts to provide proper airflow on both sides of the hotend nozzle. - M3 screws are required to install the parts. - In the case of small gaps between the fans and their housing, please use a bit of tape all around the fans to secure them during the installation - Check out the video attached to figure out how to slice the incorporated support. - 11 Dec 2025 Update: BambuStudio print profile added. If you want to slide it by yourself, please check the video linked below. A few more words: I really love designing and 3D printing, and I am incredibly happy to see how some of my projects are particularly popular online. My designs will never be for sale, however, if you appreciate my design, please consider supporting me with a tip. Thank you! Paypal.me link: https://paypal.me/adarkstudio
