Project Details

  • stampa: .............................................................................. Version 2: Improvement of the cap, integration of a thread on the valve to force it into the mask and only need to be glued on the inside. .............................................................................. It is a valve model inspired by the "nanoHack" mask, allowing to create a FFP2 category filtering mask with a pad taken from a disposable ffp2 mask. This makes it possible to make several effective masks with a single disposable mask (in case of lack, it can save lives...). You will also find a DXF template for cutting the valve support (the mask) from a polypropylene sheet (laser or scalpel, depending on your tooling). All you have to do is sew the mask beads into the mask to give it its shape, then glue the valve into the polypropylene mask and install rubber bands to hold it in place. (Don't forget to put a piece of FFP2 mask in the valve before you close it...) It is a valve model inspired by the "nanoHack" mask, allowing the creation of a filter mask of FFP2 category with a piece taken from a disposable ffp2 mask. This makes it possible to make several effective masks with a single disposable mask (in case of shortage, this can save lives ...) You will also find a pattern in DXF to cut the valve support (the mask) in a polypropylene sheet. (Laser or scalpel, depending on your tools) All you have to do is sew the parts of the mask to give it its shape, then stick the valve in the polypropylene mask and install elastics to be able to use it.
