- No need for elastic band; less parts
- Extremely lightweight;
- Easy to assemble/dissasemble; parts can be thrown into a bucket of bleach after each use
- Weight imbalance is far more noticeable when you quickly lean forward quickly; this is ampified by the thickness you use (but you can offset this by shortenin the arms and increasing the curve to the back if your head is a strange shape I suppose)
This version will use a slide in function for the mylar; so you do not need to punch any holes; just slide it in and it will "pinch" along the sides.
- no punching holes; slides in and slides out!
- by far the easies to produce and wear
In this image I used 4 mil 12x12" mylar -- with holes punched (1/4" hole) at 1.5 inch vertical spacing and as far inwards as a hole punch allows (about 1.5"). Obviously you can punch holes where-ever you please to shape to your face.
I will repost with 6mil (which is probably the minimum thickness I would recommend); I will also repost with 0.04" polycarbonate which is far thicker/heavier

Also; there is no science to this bit; I thought it was amazing that it fit my dog.

do you have an OpenSCAD of this?
