Increase the print ratio to 500%. These are two models of face shield supports. Model 1 - Ring The first is a simple ring. For each mask, you will need: 4 rings, 3 paper elastic bands, an A4 acetate sheet, and a 3x27cm acetate strip. Make two parallel holes in each top corner of the A4 sheet and the strip... join the two pieces with the four rings, pass one elastic band through each ring on either side, and use a third elastic band to connect the first two. Done! Model 2 - Stick The second is a stick with snaps. For each mask, you will need: 2 sticks, 3 paper elastic bands, an A4 acetate sheet, and a 3x27cm acetate strip. Make two holes at the same distance as the snap's on the stick in each top corner of the A4 sheet and the strip... join the two pieces with the two sticks, pass one elastic band through each stick, and use a third elastic band to connect the first two. Done!
