3D Printed Duct Fan With 775 Motor

Simple and effective 3D printed duct fan that you can build with a 775 motor. I also tested it with BLDC motor from a drone and it works great.

The only downside is that it's quite loud but that is the case for most of the ducted fans. It is quite powerful and can be used for example with lasers.

Above you can see the plots and values measured for the fan. There is a lot to optimize with a better propeller design.
