No Fan unit needed.

the extruder body you can find on thingiverse:

Beaware if you set your acceleration settings of the extruder to high this can damage the gearbox.

Firmware configuration settings

Default axis steps per unit for e_steps: 1100

Default_max_feedrate for esteps:  45

Default_max_acceleration: 300


#define DEFAULT_EJERK                 2.0    // (mm/sec)


see below an example how i have configured my firmware.


#define DEFAULT_AXIS_STEPS_PER_UNIT   {44.1644, 44.1644, 400.8877257799672,1100}  // default steps per unit for ultimaker
#define DEFAULT_MAX_FEEDRATE          {500, 500, 5, 45}    // (mm/sec)
#define DEFAULT_MAX_ACCELERATION      {9000,9000,100,300}    // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define DEFAULT_ACCELERATION          3000    // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION  300   // X, Y, Z and E max acceleration in mm/s^2 for r retracts
#define DEFAULT_XYJERK                20.0    // (mm/sec)
