Ender 3 Stock Fans Mount for Revo CR

     This fans mount allows enough room on the Ender 3 to swap  Revo Rapid Change hotend nozzles - Found here - Revo™ CR – E3D Online (e3d-online.com).  It is a remix of the .stl provided by E3D for the Revo Micro Hotend - Ender 3/CR10 Revo Micro Upgrade by E3D | Download free STL model | Printables.com.  

     Although the upgrade is drop in, i didnt like trying to reach into the fan shroud to change the nozzles.  This will also work with the stock hotend. it's nice to be able to see your hotend and nozzle.  I have included a version with supports added as well as an .obj file in case you would like to modify the supports.  This setup seems to cool quite well as seen in the pics of the print i made after installing the mount. (Please Print with Petg or a more heat resistant filament.) I have included e version without the E3D logo in case you wish to modify it.

The parts cooling fan should snap in its slot snuggly. However there is a spot to secure it with one of the stock mounting screws.

NOTE: You may have to use snippers in a couple of spots on the supported model.  Over all I found them to remove easily. Don't forget the 3 tiny model to model supports on the back side.
