Here is the link to the Onshape file where you can easily configure the fan parameters and export an STL to print. You can also make a copy of the 3D Geometry to customize the design further to meet your specific needs.
This design was originally modeled for use in the FIRST Robotics Competition (FRC) to air-cool the NEO Vortex and NEO 550 motors. Almost every cordless power tool features a fan for forced airflow, so why not seek the same benefits with off-the-shelf components?
The pictures show the design printed in flexible TPU. The flexible filament doubles as a rubber isolator to protect the motor from impacts on the field and while assembling.
The forced airflow over the motors prevents the following issues related to overheating the brushless motors:
Demagnetization of the rotor's permanent magnets
Melting of the stator winding's wire insulation
Reduced magnetic flux
Torque derates
Overall lower efficiency

If you decide to print or remix your own, I'd love to see a picture of how it turned out.
Here's a link to the Chief Delphi thread with further information and discussion.
