• Low weight (8 grams + transparency sheet)
• Low strap tension to prevent discomfort
• Fast to print (under 25 min)
• Robust
• Easy to assemble
• Wraps around the face
• Stays more than 1" away from the nose to prevent fog and discomfort

Requirements and Files

• Printer transparency or transparent binding covers (stronger).
• Trasnaprent all purpose glue. I am using the Go2 Glue with success.
• Elasic head band, approx. 5mm x 1.5mm cross section.

Assembly Process

1. Sand down the printed surface that will touch the wearer's forehead with fine sandpaper.
2. Cut the elastic band in 2 halves. Make one of the cuts where the loop is pre-glued.
3. Fold the end of the elastic band and insert into the slot.
4. Squirt glue inside the loop and along the slot.
5. Squirt a small amount of glue along the transparency guide channel.
6. Insert the transparency into the channel.
