Braun Satin Hair replacement fan (aerodynamic, fail-safe)

thingiverse

This is a replacement fan for the Braun Satin Hair air dryer. It is based on the propeller factory which you can find here: https://www.thingiverse.com/thing:4564970 The advantage of this design is that -- compared to other replacement fans -- there's a much lower probability to destroy the fan when it gets disconnected from the shaft. The original propeller has blades which are higher than the spinner. This makes it very likely that the propeller gets destroyed if it disconnects from the shaft. With this design it is unlikely that it is getting destroyed when disconnecting from the shaft. I recommend 2 component Epoxy to glue the propeller on the shaft. You can use a file to make the surface of the engine shaft a bit rougher such that the glue can connect better to the shaft. All other glues I tested so far (including glue gun, UHU Hart, ...) didn't last very long.
