You can use this 3d printed diffuser to soft the Godox IM30 flashlight.

I suggest to print using matte white filament (I used overture matte white) but you can use any coloured or translucent material to obtain artistic effects.

Scale uniformly if you want more grip, anyway it should not be needed.

Change bottom/top layers if you want less or more diffusion.

Change infill if you want reflections.
