Neste vídeo eu vou te ensinar a como dobrar
uma caixa com tampa desenvolvida por Dave Brill.
É um modelo fantástico dobrado com uma única folha de papel.
Ele tem também um ótimo efeito duplo
Se você usar um papel que tenha cada lado de uma cor.
Este modelo fou feito utilizando um quadrado de 15cm
e a medida final do lado foi 3cm.
Isso é aproximadamente um quadrado de 6 polegadas para um modelo final de 1,2.
N sua primeira tentativa, eu indico a usar um papel bem grande.
Neste vídeo eu vou usar
Um quadrado com 25cm de lado
- isso é aproximadamente 10 polegadas -
e o tamanho final do lado
da caixa será 5cm
- ou aproximadamente 2".
Então a regra é que:
o tamanho final da caixa será 1/5
do tamanho do lado do quadrado utilizado no início.
Então vamos começar a dobrar.
Nós vamos começar a dobrar com a parte colorida para cima
Para ter no final uma caixa colorida na parte de fora.
Mas é claro que você pode fazer diferente
Existe uma técnica para fazer partes com 1/5
no quadrado, mas eu não vou utilizá-la
para não ter dobras desnecessárias.
Então o que vou fazer é pegar uma régua
e marcar 1/5 do tamanho do papel
e então fazer uma dobra como esta.
Eu normalmente uso um vincador
Para marcar uma linha e deixar a dobra perfeita,
Mas isso não ficaria muito visível no vídeo.
Depois de ter as marcas, você pode "beliscá-lás".
Uma vez aqui, outra vez lá.
Mas antes de proceguir, eu esqueci,
Vamos primeiramente fazer uma dobra no centro.
Desdobre.
E agora faça a dobra no 1/5 marcado.
Vire para o verso e use as marquinhas feitas
para adicionar uma dobra no 1/5 marcado.
Desdobre e agora só temos que dividir em quartos
estes 4/5 restantes.
Traga a borda para a dobra que dividiu em 1/5.
Dobre e desdobre.
E depois dobre nos 2/5,levando a borda até a dobra recém criada.
Desdobre e depois marque o último 1/5.
E desdobre.
Agora gire o papel.
Nós temos agora que marcar quintos neste outro sentido também.
Novamente, marque.
E depois "belisque".
E dobre.
Então vire para o verso e novamente divida em quartos
os 4/5 restantes.
Na verdade eu estou fazendo as dobras
em direções específicas.
Isto não importa muito, mas
faz as coisas serem, depois, um pouquinho mais faceis.
Então se você seguir
como eu estou dobrando,
elas terão as direções de "vales" e "montanhas".
Mas se você não seguir, eu aconselharia você a
marcar as dobras nos dois sentidos,tanto "vale" como "montanha"
Então elas ficarão legais e fortes
e pelo menos elas não terão uma única direção definida.
Então desdobre tudo completamente.
Agora vamos adicionar mais algumas dobras
Primeiramente, dobre para trás este 1/5.
Agora alinhe esta dobra com o próximo 1/5 marcado.
E dobre. A mesma coisa no outro lado.
Então abra e dobre, levando a borda até o 1/5 marcado, criando assim uma dobra com 1/10.
A mesma coisa no outro lado.
And unfold again completely.
Now we've created this crease pattern.
You can see we've got a couple of mountain folds
and the rest is valleys.
Now turn the paper so that
the central crease here lies horizontally.
Then this is the top, and this is the bottom.
We're now going to add creases to the top.
Diagonal creases, some here, here, and here.
Fold the diagonal of a square with a side length of 1/5.
And also diagonals right here.
And crease the other diagonal.
Unfold and then fold the other two diagonals here.
Now we added diagonals to those three squares.
These creases need to be a bit stronger.
So fold them as mountain folds, too.
In the bottom we'll also crease the diagonals of the central square.
Now we'll add some diagonals right along here.
For this aling the lower point
with the point at 1/5 by 1/5.
Crease starting from the center
one square up.
Unfold, repeat on the other side.
Align, starting from the center
crease one square diagonal up.
Then rotate and repeat.
Unfold and rotate back
so that the top is in the top.
Next we're going to make a precreasing here.
So we'll add half a diagonal
or a diagonal on these
small squares, which have 1/10 by 1/10 side length.
For this bring that edge to 2/5
and then crease just along that small area.
It's not the first 1/10 square, but the second one.
Unfold, repeat on the other side.
I'm doing a lot of precreasing here,
because I think it's great to use this for a present.
Then you really want it to look very nice.
Rotate again.
You can see we added this crease.
And now we want to add that other diagonal.
So, again take the edge, bring it to 2/5,
and this time crease
that small square by the edge.
Unfold, repeat on the other side.
And unfold again.
Let's add one final set of creases.
Using the creases we just created as a reference,
we're going to add 1/20 right here.
Flip over the paper to make a mountain fold.
You can see, here's the crease, this length is 2/5.
Here there's 3/5.
This is the top, this is the bottom.
Now crease 1/20 only up to
those creases we added last.
You can see I stopped creasing right here.
Do the same on the other side.
Now - I know it's hard to believe -
we've got the crease pattern done.
I'm going to add one last crease
in the end, but let's not worry about that now.
So first let's locate the top and the bottom.
You can see the top has three of those
squares with diagonal creases.
And the bottom only one.
Then fold in 1/10.
The're already mountain folds, or make them into mountains now.
Then fold up, so this is perpendicular
on each side. In the middle 1/5 will remain.
There are diagonal creases here.
We're going to make them pop up
in a mountain fold.
Like that, can you see this?
Maybe make a valley fold there, too,
so that you can see this happening.
On the second one, right here,
you're going to fold down
to collapse like this.
I hope that was visible.
So you get the start of a box.
Now I did forget to add one final precreasing that I usually do,
so let's add that now.
You can see 1/10, and then there's 1/5.
On that square we're going to add a diagonal crease.
Let's do that now.
Just like that.
Same on the other side.
Adding that diagonal.
With this being collapsed
you can insert one of those 1/10
into the other one. Slip it inside.
It will help a lot
to reinforce that these four layers of paper
are all in line with the creases we prepared.
These are going to be valleys.
As you can see I'm just pressing on them through all layers
to get them reinforced.
Then you get a shape like this.
Now we'll take this point
and push it back so that
the triangle will lie like this.
This is going to be a mountain fold.
And we're going to push this
inside to the back.
So if you look inside
you can't really see much
because the triangle actually lies
right along this layer right there.
Let's have that in place.
Then we'll push this layer
so that it lies right on that one.
I usually support the paper a bit by putting my finger in there
and then pushing down.
Push down, it may start looking messy here,
but don't worry. Just keep on pushing
pushing, pushing, pushing
and it will straighten out beautifully.
There you go.
Reinforce these creases a bit.
Now you can see the lid is almost complete.
You've got some creases here.
This is going to be a mountain fold,
and those are going to be valleys.
This completes the lid.
Same on the other side.
There's a mountain, and a valley.
And it goes like that.
Some directions of the precreases aren't that important,
because there's two layers, and half of it
will be the wrong direction in any case.
Once you've prepared that
you can have a look at what it's going to look like.
So this would be the lid.
But we're going to clean this up now.
These small triangles
right here are going to go underneath
that layer, so that it's nicely hidden and
the paper has more space to actually lie nice and flat.
The triangles are hidden now.
You can see that there's a crease right here.
That's the central crease we added (in the first step).
Let's fold back along that.
It gives the model a bit light again (for the camera).
Sometimes these layers aren't quite aligned.
So I like pulling then apart a bit to get them aligned.
It will give a nice finish in the end.
Now we need to complete this box here.
We first have to get these layers back up.
to form this rim.
It ensures that the box closes nicely.
So we'll take just one layer of paper by going in here
and pulling it up.
We've added some diagonal creases right here,
we'll go along those.
That's number one, and again take one layer
pull it out, and straighten it out.
Reinforce that crease.
You have creases right here, they should be mountains.
We're going to fold those to the outside.
Ensure that these two layers here
stay together to get a nice finish.
Then pinch that corner.
Same on the other side.
And pinch that corner.
In the beginning I promised we'd be adding one final crease,
which I think Dave Brill doesn't suggest.
But I'm going to do that anyway.
So on the right side, we'll take two layers
and fold them down to the edge.
This is going to make the final locking mechanism
a bit easier to do, I think.
And easier is better, right?
So, let's keep that.
Now, as in the beginning, we're first going to make
one mountain fold like that.
We're pushing this up in a mountain fold
and pushing this to the back.
And fold the other one down.
You can see a triangle emerging here.
We just folded that small corner. this one.
I'm going to pop that up and
put it behind that triangle.
I'll try to make this more visible.
Can you see that here?
The white triangle is underneath that small corner we folded.
Now the box is basically done, but
this is still not fixed enough.
So what we're going to do is take
this one layer and pull it up by pulling in the top.
And then take that triangle that we just folded.
You can see here you've got the triangle,
you've got that small corner we folded over,
and here there's some space.
So we're going to take this layer
and insert it there.
So pull this, and then just put it over there.
That folded in corner makes it a lot easier
to actually insert that layer.
Now the box is a bit more fixed,
but again, here's a tiny corner.
And for that we're just going to
put this layer underneath that layer.
Underneath here.
This can be a tiny bit fiddly,
but it's the final step.
So that shouldn't be too bad.
And then your box and lid
from a single square of paper
designed by Dave Brill
is all done.
I usually close the box halfway
and then reinforce those folds right there.
to make it really nice.
Sometimes when I close the box I have a dent here.
Then take for example the back of a spoon,
go inside, and pop it out.
And then it looks nicer. On the other side it was fine.
And there you go.
I hope you enjoyed this video.
and this fantastic box and lid by Dave Brill.
Happy folding.
