2212 Motor cooling impeller - note caution is warranted with the cooling impellers - the layer adhesion issues inherit to 3d prints makes it possible for the impellers to fracture under load. Wear eye protection and be mindful of risk when using. For added safety consider printing cooling impellers in TPU - higher layer adhesion should make failure less likely.
These impellers are known as backward curved impellers and work somewhat counter intuitively, even if installed incorrectly they will still blow air out radially (as a forward curved impeller) but are most efficient in the backward curved orientation. The correct orientation is indicated via rotation directional arrows in the print.
Printed in PETG with 0.4 mm nozzle and 0.12 mm layer height - reduce print speed to increase layer adhesion.
