#757CARES Face Shield MK2.2

prusaprinters

<p>Change History:</p> <p>Dentists' offices needed the transparency much further away from the face to make room for lighted loupes. I added an extension that snaps onto the headband which moves the transparency 57mm further out, while still providing overhead coverage. Loupe Extender Mk1.6 is added to the file library.</p> <p>Elastic became scarce, so I made this "slip nut" sized to be able to use paracord which is available at any home improvement store. Two sizes provided for popular sizes of paracord. 550 is for 5/32" (4mm) paracord and 650 is for 1/4" (5mm) cord.</p> <p>2.2 doubled the polygon count on most of the model to improve print quality and speed. Spread stems out 5 degrees each to allow for closer nesting.</p> <p>2.1 Corrected position error with 3 hole pins. Extended tabs on temple pins, modified elastic slats.</p> <p>2.0 Modified original #757CARES design to include a forehead shield (brim), moved from a 4 pin to 3 pin design to support standard 3-hole punched film, changed elastic hook to accomodate slats for 1/4" elastic bands.</p>
