RS Cooler Remix for Revo CR

 

Find the original [here.](https://www.thingiverse.com/thing:4170231)

This is a remix of the Red Squirrel Compact Fan Housing for Creality Ender 3 3D Printer by Red Squirrel Hobbies. The Red Squirrel is my favorite cooling solution for the Ender 3.

Changes From the Original
  • This remix is based on my previous remix of the Red Squirrel Compact Fan Housing. That remix split the cooler into 2 parts to facilitate easier nozzle changes. This is no longer necessary using the Revo hotend and nozzle.
  • Space was made for the larger coolign fins on the Revo CR. The "chimney" has been removed in favor of a simpler cable anchor point.
  • The part cooling ducts have been made a bit rounder, and space was made for the Revo Core's strain relief to pass through to the right side of the cooler.
  • More openings for airflow around the find have been added and the clamp piece was removed.

A generic base lock is included. This should be compatible with other Hero Me mounts.

This cooler should work well with the original Ender 3 hotend as well.

The intake scoop for the radial fan is optional,

This cooler should work well with the original Ender 3 hotend as well.

A step file is included should you need to modify anything.

Print with the fan end facing upward.
