Flashforge Extruder Turbo Fan

What is this?

A fan for the 3D printer.

Why did I buy it?

My Monoprice 3D printer didn't come with fans for either of the two nozzles, and without a fan I can't properly cool my prints - resulting in ugly blobs and imperfect lines.

I purchased this fan upgrade and was quite disappointed to find that not only did it lack instructions, but it only cooled one printhead. I finally figured out how to connect it, and it does work, but it was a disappointing experience and somewhere down the line I'm going to 3D print a fan shroud upgrade to replace this.
