2think Face Shield Frame (PRUSA Mod)

I made a few modifications to the Original PRUSA designed Face Shield to improve comfort and durability. They include:

* Split and Tapered the forehead contact band - this improves comfort over a longer period as the "wings" will bend and more conform to the wearer's forehead

* Extended the temple rails further back to "hug" the sides of the head more - facilitates more lateral stability

* Added small lateral connection supports between the ends of the front outer band and the forehead band. This resists any torsional motion during head movement

* Created loops at the end of the rails for a more comfort transition away form the head when holding the retention strap (recommend latex tubing 15" long for strapping material 3/16" Outside diameter with a 1/16" Inner diameter)

* This version of the the original PRUSA deign is intended to work with 8.5" x 11" transparent "Binding Covers", 7-10 mils in thickness. Punch (4) holed in the covers, 1" down form the top. Mea
