3D model description

This is a replacement turbine that fits the Powerfun EDF ducted fan motor.

I broke the original turbine in a crash of the prototype Jetfan flying wing model available in my profile.

This fan is a little different than the original in that it was designed for 3D printing.

The manufacturer states that their fan blades have to be dynamically balanced. Unfortunately that renders the fan motor useless if you break a blade. I have successfully run this EDF with the replacement blade and experienced no unacceptable vibrations. Use this at your own risk.

3D printing settings

This is for resin printing only! The parts are far too small for FDM printers. Also you will never get the balance right.
I had success using just a standard grey resin
