We are making a sip and puff straw adapted
KN95 mask. We'll start with an unmodified mask just straight out the
box, KN95, and the first step is to measure
out your hole punch location. so for most people
from the top arc down two inches works really well.
You could up that by an eighth of an inch or lower it by an eighth but
usually two is good. So that's right here,
and then from the front arc of the mask, you'd measure around, 1 inch works best
for most, it could be 7/8ths or 9/8ths but 2 inches down,
1 inch away from the front arc works best.
Mark that with either a pen, pencil or your thumb.
So that's where i'm going to punch the hole.
The next thing, you have this grommet setting tool you can get online,
it comes with your top and bottom half of your grommets,
the mandrel, setting die and your hole punch tool,
which is black with a silver sharp edge, this is what we use to
punch the hole, the black tool, so
I'm using an eraser, but all you need is a firm durable surface that
yields a little bit, you can use cardboard
boxes, a heating mat, anything that is handheld, durable and yielding.
So, i'm gonna take that surface, an eraser in my case,
hold it on the inside of the mask, it's used to protect your fingers from
getting cut by the sharp edge, then where you've marked your ideal hole
punch location, center the sharp edge of your hole punch
tool around that, and then press firmly
and twist. So that's what i'll do now.
The hole is punched.
The front looks like that.
Inside looks like that. So you can set this tool
aside. The next thing you'll do is align your
grommets. So i'm taking out a top half grommet right now
it has a rounded front and a really small cylindrical back edge
to it that's going to be the front facing side of the mask, so you'll see it
on this side. You want to align that with the rounded
side down onto your setting die, it's a short metal
cylinder, so aligned like that.
Face that down, then you'll take the front side of the mask
where you've punched your hole and you'll align the hole
around the top of the grommet that's sitting on top of your
short metal setting die
Now I'm getting a bottom half of the grommet.
It's going to be on the inside of your mask.
So you'll take the bottom grommet eyelet it's a small cylindrical disc, it does
not have that straight cylinder sticking out, it's
just a flat disc it has a slightly flatter edge and a
slightly rounded edge, you want the rounded edge
to be facing this long metal cylinder tool.
So face that down and then
you have where you've aligned the top grommet on the setting die,
the mask hole around that
bottom grommet eyelet and then long metal setting tool.
And then you'll hammer that entire assembly down.
That's done. I might have hammered a little too hard.
So that's the set grommet that's finished. This is the front.
The inside of the mask looks like that.
The last step is to insert your silicone straw hold grommet
with an attachable plug.
You can get these online, they come in 40 per pack
for around nine dollars. So what you want to do
is make sure that from the outside of your mask,
this plug is closing the mask. the easiest way to do that is to take
the plug and from the inside align the plug
so that the attachable line part of it is parallel
with your mask top and bottom or the line on your kn-95
once you have that plug aligned, insert the silicone within the metal grommet
and then make sure that the silicone on both sides is hugging each side of
the set metal grommet of the mask. So that's done. This is what the finished
mask will look like with the plug open.
Front, inside and this is what the sip and puff mask
will look like when plugged.
And that is your finished sip and puff straw modified KN95 mask
