A jet engine nosecone spiral inspired series of 5010 blower fan covers to provide a quick visual indication at a glance if fan is on or off. Determining if the Sunon 5015 blower fan I use for part cooling is spinning is very difficult since the fan and case are the same black matte black color and the fan is slightly recessed in the housing. I wanted a quick way to see if the fan was on or off, so I designed these jet engine inspired spinners. If you want to change the background color of the cover cutout, I have provided a color disk that you can print in a contrasting color and place in between the cover and fan hub. Jet engine spinners help ground crews determine if a jet engine is spinning for safety reasons. They also help to scare birds birds away.
