Model origin
The author remixed this model.
Differences of the remix compared to the original
This remix relocates the fan and guides the airflow to maximize coverage of the motor.
The fan mounting holes for M3 screws were replaced with a friction slide. This enables the fan to be pushed out of the way to access the extruder lock lever.
This Remix uses a smaller and lighter 3010 fan. Some other models use a 4010 fan. In my opinion that is too big. Those add weight to the extruder and are so big that there is a greater risk of crashing into other parts of your printer.
