Covid-19 Faceshield (A4 Clear-sheet compatible headband)

UPDTE 4/9/2020: Alternative version uploaded with thinner bands (1.6mm vs 2mm). Print time reduced to 1h30m. More flexible but still durable enough.

FIY 2 pieces can fit a Prusa i3 bed when mirrored and rotated 45 degrees. See the Image for layout.

Description:

Inspired by a variety of similar designs found online.

• Low volume, fast print (1h 45m with PETG filament and 0.3 mm layer height, 0% infill, 3 perimeters! with 0.4mm nozzle)

• Designed to work with A4 transparent (PETG or PVC) sheets. Snap-on mounting via four 5 mm punch holes evenly spread 80 mm apart (standard for the A4 long edge binder hole punch). No glue needed.

• Three arc design providing a better fit and more room around the face (easily fits mask, and glasses underneath).

• Three slots for easily mounted and adjusted elastic band (works with a non-elastic band too)

Full disclaimer: THIS IS NOT TESTED FOR PROTECTION!

Some sources suggest better protection when the headband arc is filled on top around the forehead. This is intended as a low-end safety measure. It primarily acts as a reminder not to touch your face and as such, it works really well :)
