covid 19 mask clip
Description
Clip to make a protective mask. I used TNT (TNT is the acronym for the Italian Tessuto Non Tessuto, which in English translates to Nonwoven. In German it translates to vliesstoffe and in French, non tisse.) This cant protect you as FFP3 respirators. Not for protection against viruses. The mask avoids spraying the droplets to contaminate others. The filter: 4 TNT sheets of 27 cm x 20 cm. I used the screws because in this way it is possible to use several sheets of TNT together and it makes the clip more resistant. Assembly N. 4 screws - M3 12 mm N. 4 nuts - M3
