This is a replacement concentrator for the T3 Micro Fit Hairdryer. (OEM version here)
The original is brittle and has quite a few weak spots. You'll notice this replacement isn't an exact replica - mostly because 1) I'm not great at this and 2) I wanted to make it stronger. It should just snap on to the the end of the hair dryer.
I've found the ColorFabb Ngen filament works well. It has a glass temperature of 85* and isn't causing any deformation for the length of time I use the hair dryer. Your milage may vary.
Edit: I printed another one using ColorFabb HT. It was a bit tricker to print, but the higher glass temp of 100C makes this work better for longer use periods. I highly suggest it over the previous one
