Here is my rendition of the Ender 3 V2 Fan Shroud.The Lowk Shroud. This was designed at the same time as the Lowk Body kit.
You can access the Lowk Body kit you see in the pictures in my designs.

The Lowk Shroud is designed specifically for the Ender 3 V2 but should be compatible with the Ender 3 (Not Tested)

The Lowk Shroud comes in several different variations and is compatible with both standard and CR/BL Touches.
The shroud black fan cover you see in the pictures can be printed separately and then placed over the shroud seamlessly.

Please take note of the thickness of your hot end fan. If you would like your fan cover to fit on smoothly you will need to print the corresponding shroud that fits your hot end fan.

Note: When 10mm or 20mm is mentioned I am speaking strictly about the thickness. ( 40x40x10mm or 40x40x20mm)

Example: 20mm thick hot end fan will need the 20mm fan shroud
Example: Printing a 10mm shroud for your 20mm fan will not be able to fit the fan cover.

The Shroud requires the stock nozzle fan to function if you do not have the stock fan any more here is a link.

Special Slicer Instructions:

-Non CR/BL standard shroud can be printed as is with out support

-Cr/BL shrouds needs support. You will need to use a support blocker so that supports are only printed below the screw mount on the left side and no where else other wise the shroud will be unusable.
