Anet A3 fan vanes (heat sink replacement)
thingiverse
I've been running my Anet A3 for over a year now and I'm still not entirely convinced that the stock heat sink is doing its job effectively. The small surface area of the stock heat sink, which only partially touches the extruder, makes me wonder if it's truly efficient. Therefore, I decided to conduct an experiment. This upgraded heat sink replaces the stock version and directs airflow from the cooling fan directly into the extruder and face of the stepper motor.
