Description

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 Sand down the printed surface that will touch the wearer's forehead with fine sandpaper. Cut the elastic band in 2 halves. Make one of the cuts where the loop is pre-glued. Fold the end of the elastic band and insert into the slot. Squirt glue inside the loop and along the slot. Squirt a small amount of glue along the transparency guide channel. Insert the transparency into the channel. More information in my blog (http://rdimitrov.twistedsanity.net/blog/show.php?entry=Making%20a%20Coronavirus%20Face%20Mask).
