A3 Face Shield no hole punch (Aegis mask Cardiff remix)

thingiverse

Taking inspiration from brilliant designs by Hanoch Hemmerich and Aeneas Solis, I crafted a face shield that employs A3 size acetates (29.7 x 42.0cm widely available) which offers significantly more protection than A4 sheets. This design necessitates no hole punches and wraps snugly around the head. Smaller plastic sheets can also be utilized.

If you opt for a lower or higher infill, the print time will increase accordingly.
