Dual Face Shield using 3 hole sheet protector

First post to Thingiverse. After seeing some incredible shield designs on Thingiverse I was struck that it seemed no one was taking advantage of pre-cut and pre-punched plastic sheet protectors to act as a shield. The design I have made holds either a sheet protector or a rigid shield. Can also use a 3 hole punch to make holes on clear plastic sheets.

When using off the shelf sheet protectors, depending on the quality of the material for transparency, it may be needed to remove one layer simply by tearing away along the two seams. The length of the shield wil double and can be used as is or trim.
