Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4996762.
Put on and wear the mask like a pair of sunglasses. I've uploaded the nose bridge and the right ear piece. Mirror the right (in your slicer) to create the left. Attach to the mask with a 3D pen or hot glue gun, and adjust by heating up with a hair dryer. (you might be able to just use the hot tip on the 3d pen or glue gun to attach, without extra filament or glue. That's how I eventually attached the eye grills to the original mask), The mask is heavier than a pair of sunglasses, so will still need an elastic cord to help keep it in place, but this may help with comfort.
I used TinkerCAD and this model https://www.thingiverse.com/thing:4114095 to create the bridge for the nose, and ear pieces and than attached them with a 3D pen.
I printed these with a 0.6mm nozzle (cause it was already in the printer) with PLA+.
The file I uploaded that says DO NOT PRINT... its just for the preview and is not meant to be printed.
