A3 Face Shield no hole punch (Aegis mask Cardiff remix)
thingiverse
Taking inspiration from brilliant designs by Hanoch Hemmerich and Aeneas Solis, I designed a face shield that uses A3 size acetates (29.7 x 42.0cm widely available) which provides considerably more protection than A4 sheets. This design require no hole punches and wraps right round the head. Smaller plastic sheets can also be used. Construction video here: https://youtu.be/2JEADY4SrO0 I based this on designs by Hanoch Hemmerich and Aeneas Solis here: https://www.thingiverse.com/thing:4238890 https://www.thingiverse.com/thing:4233193 REVISION HISTORY v4 - Increased front lip distance to stop fusion. Increased size of hook arms to aid bed adhesion. Decreased side grip diameter to better grip acertate. v3 - Removed fillet on bottom to aid bed adhesion v2 - Increased size of hooks on end of arms to help bed adhesion v1 - Original At 30% infill on an Ultimaker 2+ the print time is 2hrs 34. If you go to a lower or higher infill the print time will increase.
