Based on the MBOT3D MK2_Rev2.0 by Ahmad Sunardi, I have designed this Dual Blower Fan Duct for E3D's RapidChange Revo CR Hotend installed on the Ender 3 V2 3D Printer.

You can install it on a Direct Drive as well as Bowden setup.

The magnetic lid allows for easy access to your hotend.

It allows for better part cooling, increased print speed and quality!
