Was making a mask from the Toribor's model of the Cyborg Ninja Grayfox Mask from Metal Gear:Solid (found here: https://www.thingiverse.com/thing:2557764/files )
But I needed a center part to hold a 5mm LED and its holder. This did the trick for me.
Depending on your print settings, you may need to nudge it here or there in scale. The inside lips of the mask are slightly chamfered, so the 2 LED Plate file has a radius on the lip. The other is just a squared off cylinder
