2think Face Shield Frame (PRUSA Mod) by kwilley_7662

Last crawled date: 4 years, 1 month ago

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

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


Tapered the Spit "wings" to better confirm to the forehead backward slope


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. Measure from both sides of the center line of the cover (at 4.25") - 1 3/16" and then from center again 3 3/4". Then with a 1/4" hole punch, punch holes in the cover using these marks as the center point of the punched out hole. (Please see attached pic for a better explanation).

Feel free to use rubber bands to add a bit more holding security to the top of the binding cover by stretching them around the small tabs protruding through the transparent cover, from side to side.
