Hair Dryer Diffuser i modeled for myself. PRINT IN TWO PIECES (LowerHalf and UpperHalf), NEEDS SUPPORT, adjust rotation before printing to ensure only the inside of the diffuser gets messed up by support. Fits on hair dryers with external nozzle diameter of around 55mm- 54mm (seems to be a pretty standard size) The Snap Fit Design might need some more iterations before it works well, so included the solid edge Part files, for anyone that wants to improve this.
