Anet A3 fan vanes (heat sink replacement)

I've been running my Anet A3 for over a year and I've never really been overly confident the stock heat sink has actually been doing that much. It has such a small surface area touching the extruder and the little that is is so thin I have to question its efficiently, so i decided to do a little experiment.

This item replaces the stock heat sink and guides air from the cooling fan directly into the extruder and face of the extruder stepper motor.

Print as is with no supports, any layer height should work. my print was done in ABS at 0.2mm layer height.
