This 3D Flat Brimmed Face Shield has both the pegs to accept 3 hole punch sheets, a custom slit to tuck in the end of the sheet, and a flat brim to provide full coverage at the top.

This was created by incorporating the best concepts from the DtM v3.1 and IC3D Budmen designs.

The key features are below:

• Flat brim to allow for full coverage at the top, preventing droplets from falling through the forehead area
• Sufficient spacing away from face to accomodate goggles, allow for personal comfort
• Uses hook system to attach elastic (can use a rubber band, buttonhole elastic, etc)
• 3 pegs for standard 3 hole punch attachment
• Built in slit to tuck in shield to keep curvature throughout the shield without the use of a bottom piece
• Allows for foam cushion to be adhered onto the forehead band
• Design can be worn either way (there is no difference between up and down)

Instructions for Assembly

2. Attach transparency to headband on the three mounting pegs.
