LED diffuser shell

I have been making multi-panel lights from LED chips and wanted a diffuser that could be placed over the electronics to soften the light. The shell can be resized as needed and has a small ballast across the bottom to hold the unit in place along with gaps for air circulation around the LED source. This will have to be printed in either a translucent or clear filament. The V2 version has a hole in the center of the ballast to channel wires through.
