Custom flash diffuser for pop-up flash of Nikon D7200.
Since version 2.2 it will fit other cameras as well due to the sliding slot: you only need one M3 nut and one M3x8mm screw.

I used this fantastic design for the flash mount, many thanks to @TheCase.

It will be better to print it with a translucent filament, but the white colour is however a good choice.

Update v2.2 (thanks to @BikeCyclist for suggestions)

• cut the dome for easily print
• add sliding slot in order to fit other cameras
