Respirator mask with bike tube seal and vacuum bag filter · 模型 195291
Respirator designed to be made from things that you can find at home. bike tube -seal vacuum bag -filter PETG -body ... and some tape The inventive part of this design is the bike tube seal. It is made using accessible material and it adjusts to the shape of face easily. Large filtration area allows for use of vacuum bag as filter. Seal works great for me and friends i tested it on. Its not for kids ! Breathing is not perfect. I did some very light biking and it was ok. When i tried to move furniture in it, it got wet and i couldnt breathe through anymore. I believe that it is as good as you can get with vacuum bags. You can use different filtration material such as medical mask, and that is a whole different story. Good breathability and seal. DISCLAIMER This is uncertified, untested design. If you have certified protection available use that instead. Use this design on your own risk. After 5+ hours wear, tube causes skin irritation. PETG parts BODY You can choose UNIBODY is made in one go. +solid WITHmesh + mesh is done in two prints. +less surface for breath condensation -adds funny vibration to your voice /may be a + for some :) / They were ment to be printed without any support. Howether sometimes they break off so i would advice to use a BRIM /not for mesh/ CAP you can choose again both caps are interchangeable, one is slightly more cool :) printed without support of any kind. You might ask what is the shield thingy at the bottom. It is there besause my feeder got fillament all curly when printing separate fine mesh lines. CLIP 2X you can print with other parts BIKE TUBE parts One mountain bike tube should be sufficient for two masks. Wash it well before use. First, inner piece of tube is made into a loop roboros style. one end is put into another about 2cm deep. You can put this piece into the slot easily. Place the intersection in the bottom middle. it is roughly 38cm long, but have some reserve. Second piece is roughly 36 cm long. It is to be inserted in a U profile, and you will need a blunt tool to insert it into the slot, secuting first piece. I used swiss army knife flat screwdriver. Be gentle. Start at the bottom part at the intersection and work your way around, shorten your tube to just touch the intersection. Now secure the intersecion with extra piece 1 layer U. this way 6 layers of rubber will be present everywhere. DV mask /black/ on pictures uses 4.5cm wide tubes TRI mask /grey/ on pictures uses 3.2...
