Hello, and Welcome to our Sonobe 8-pointed module (octahedral unit) video
So this model uses
twelve (12) Sonobe units
We're going to use three different colors, four
units each
If you don't know how to make a Sonobe
unit, check out our video on that
So first we're gonna make a
valley fold as we're showing here
Then open up the piece
and make two more valley folds with the
points, as we're gonna show here
Note that the pockets of the unit should
be underneath
the piece at this point
Okay, crease that well
Make twelve of these
They could all be the same color, but we're going to use three different colors,  four units each
So start with one unit of each color
and take the first two units, hold them
perpendicular to each other
Put the...
...flap of one unit into the pocket of the
other, like we're showing here
then grab the third color
insert that into the pocket of the
second piece
then take the tip of the first piece and insert it into the third piece
So when you do this
you'll end up with a three-dimensional
shape
Make sure you tuck it all the way in
So it looks like a triangular pyramid
You see the triangle, and it's coming to a
point
with three different colors at that
point
So now make a second identical
set of three
We're going to put these two together
so what we want to do
(and there's more than one way to put them together but) we're gonna
have the colors opposite each other,
so yellow opposite yellow, pink opposite pink
and brown opposite brown
So just start sticking the
points into pockets like we're showing
here
So now we're going to make a second
unit like that, and we're going to join the
two together
so you can see from the tops here, the
layout of the colors is identical
so if we joined them together like this
the yellow wouldn't meet yellow and we
don't want that actually, we want
opposite colors touching, so we're gonna
rotate the right piece so that we get
brown
opposite yellow
and now we're just going to start
sticking the
tips into pockets so
brown goes into yellow
and then we'll do the one nearby which is yellow into pink
You can see that forms a little pyramid right
there
And now we're just going to go around the piece
Tucking those points into pockets
where we can find them
There will be a total of eight
of these actions that join
the two halves together
So just go around the piece
Get it as snug as you can
Now here the yellow point is inside
the piece, we need to bring it outside
So carefully bring it out like that
put that in 
the pink pocket
Alright now this brown flap is inside
the piece as well, so we'll bring that out
stick that into the yellow
and this yellow piece goes into the pink
Now we just go around and make sure everything is tucked in nice and tight
And there you have it
your Sonobe 8-pointed Module (Octahedral Unit).  Enjoy!
