This is a centrifugal fan. It needs a lot of rpm and power. It has a nice UFO look. You can touch the top while it spins :)

There is also the adapter for a 5mm axle 775 motor.

Be careful though when you play with 775 motor and plane, always stay out of the rotation plane and wear protective gear.

No support needed but a random starting seed for each layer is nicer.
