Quadra ConVase 2 - The Two-in-One Transformer

The Two-in-One Transformer - They are one and the same!

The one on the left can be transformed to look like the one on the right just like a transformer, in minutes if not seconds; vice-versa. You really have to fold one to understand the mystery and enjoy the fun!

With the knowledge you acquired folding the previous models, may be a few photographs will be sufficient. Let me know if you needed any helps. 

 Gently  expand the four walls only.

Separate the adjunction sides by pulling apart the central pointed joints to reveal the hidden folds. Take great care not to tear the corners. 

A fully expanded "Two-in-One Transformer" Quadra-ConVase

Quadra ConVase 1 - The Basic Model

This is the simplest Quadra-ConVase. It looks balanced and is the base model for all my Quadra- ConVases.

Step1
Prepare an "Origami Square Base" with the four open tips facing up.

Bring the right corner to touch the Vertical Center Line (VCL)，align the edge of paper along VCL towards the top open ends. Crease to form Line A1.

Step 2
Bring left corner to touch VCL，align the edge of paper along the VCL towards the top open ends. Crease to form Line A2. 


 

Step 3
Bring the base-tip up along VCL to touch the base of the triangle formed with the  two previous steps. Crease to form the quadra-base.

Step 4
Open the triangle. Bring the right corner along the Horizontal Center Line (HCL) to touch Line A2. Crease to form Line B1.

Step 5
Poke a finger between the two layers of paper and separate them along Line B1 towards the left and right respectively. Crash-fold to form a triangle as follows:

Step 6
Back flip and cover up the triangle.

Step 7
Bring the right corner towards the VCL, align the edge of paper along VCL, fold along the pre-creased Line A1 towards the top open tips. 

 Step 8
Fold back the back flap along Line A1 as well. 

Step 9
Mirror-fold Steps 4 to 8 for the other three sides. 

Step 10
Fold down all four tips along the VCL.

Step 11
This is the moment to witness the magical transformation of the Quadra-ConVase.

Foundation of Origami ConVase - The Square Base

All my ConVases are based on the common Origami Square Base.

For the benefits of beginners in origami, I have decided to demostrate it's preparatory steps here. There are many other ways of achieving the same thing.

Step 1

Use a square paper, pre-crease four straight lines in accordance with the following picture.  Fold in the direction towards covering up the visible lines. This will make subsequent folding more smooth and natural.

Step 2
Fold along the diagonal line, forming a triangle. 

Step 3

Separate the two layers of paper from the right, bringing the pre-creased line towards the left, at the same time bring the right corner to the top, forming a square naturally.

Step 4

Turn the paper over, repeat the above steps. 

That completes the "Origami Square Base". 

You should have four tips at the open-end at the top. The pointed tip at the bottom is the center of the square paper.   

I shall refer to the vertical line as the Vertical Central Line, VCL, and the horizontal digonal line - the Horizontal Central Line, HCL. 
This is just for easy reference  to facilitate easy instructions; you need not actually draw them as they are already formed when you pre-creased the paper. 

Basic Octa-ConVase Variations- Mouth, Base & Wall Gradient

Two Extremes of the Octa-ConVase Variations

Designing the alternate Octa-ConVases is basically a study of the effects of changing the area of the octa-base and the mouth, and how they affect the gradient of the wall. At times, one may focus on the gradient instead-such as to fold a model with up-right vertical walls. 

It is the same piece of square paper, when something gains, others have to give. The most noticeable resulting varience is usually the height of the model; and it also makes the models look tall and thin or short and fat.  The picture above demostrates two extremes of the Octa-ConVase variations. 

 How to Change the Base Area?

The control is in Step 2. 

The picture shows the two extremes I would recomend. The resulting models look similar to the two in the picture above. 

You can of course use anthing in between. Beyond the extreme limits, the model will be technically wanting. 

How to widen the mouth? 

The control is in Step 9.

I trust the picture is self-explanatory. The one on the right is the standard model. I don't recommend widening beyong the Vertical Central Line (VCL), as this makes the top edge too narrow. 

 

Mouth Variantions: Standard vs Wide

And here is the top view:  

 

 

 

 

 

 

 

 

That's it. Want more challenges? Try folding this one with all folds hiden inside the model making them invisible, giving you a clean and zen look:

  

 

Till we meet again. Enjoy.

Folding the Standard Octa-ConVase

Octa-ConVase variations folded with same procedures

You have seen some members of the Octa-ConVase family, lets now try folding the "standard Octa-ConVase". 

By "standard Octa-ConVase", I take into account its aesthetic appearance and general useability, as well as technical issues in the designing of the folding procedures.

A tall ConVase with a small base is nice for display, while one with a big opening and wide base is most suited as a waste collector on the dinner table. Opinions differ and it all depend on the actual purposes of the finished product. We will look at folding the variances in future.

Step 1
Prepare an Origami Square Base.
(Please refer to the article - "The Foundation Of Origami ConVase - The Square Base", in this blog for folding instructions). 

With the open-tips facing up mark a vertical line and horizontal line. I shall call this Vertical Central Line (VCL) and Horizontal Central Line (HCL) respectively. 
 

Step 2
Bring the bottom closed-tip to touch the HCL, crease and unfold. This forms your octa-base.

Step 3
Bring the right corner to touch the VCL, align the edge of the paper  along VCL towards the bottom tip. Crease.

Step 4
Seperate the two layers of paper from the creased line, bring one side to the left and crash fold. Now your model should look like this:

Step 5 
Flip and cover the visible triangle. 

Step 6 
Flip the paper to reveal the HCL at the back which now appears slanting, and align it precisely with the cross at the centre of the paper. Crease to form a line from the end point of the octa-base created in step 2.

Step 7
Unfold. 
Bring corner to line formed in Step 6, align edge of paper along the line towards the octa-base,  creased. 

Step 8
Mirror fold Steps 3 to 7 for the other three sides. 

  
Step 9

Fold along the doted line as shown in the picture for Step 8. Mirror the same step for the left hand side.
  

 

Step 10
Repeat Step 9 for all four sides. 

Step 11
Fold down all four pointed tips and reinforced the octa-base created in step 2. 

Step 12

You are done. 

Now is the moment to witness the magical transformation of the Octa-ConVase. 


 







Congratulations!......

Now you can go on and try folding the variations.......................
