A diffuser panel designed to fit the Great Video Maker GVM-480 LED lights. While some of their kits come with one, this can be added to the barn door variants, and can be used with or without the barn doors attached.

These mount magnetically on the thumbscrews that the barn door normally uses - I prefer using those thumbscrews (M4 machine screws if you need replacements), each with a 5mm spacer (model included, printable on the same settings as the diffuser) to make them taller off the face of the light, then using a small neodymium magnet on each of the corners to hold the diffuser to the head of the thumbscrews.

I use mine with the provided diffuser that mounts directly in front of the LEDs still installed (as pictured).

Print from clear filament and you will usually get a translucent print like pictured. Using smaller layer heights or few perimeters will generate infill material (the pictured prints have none generated) which will effect the way it performs. For clearer panels, use some overextrusion (5% is a good start) and higher temperatures. Normal PETG profiles and 200um layer heights should give you at least the same ballpark as the pictured prints.

If you want better diffusion, you can use a white filament (especially if translucent white), but the color can effect of the color temperature of the light coming through the diffuser, and it will block much more light with a non-transparent filament used.
