ANOTHER TRIANGLE WALL TWIST BOX

Once started on a mission to create something I frequently end up creating several different things as a consequence of the mental stimulation. Sometimes the connection is clear, sometimes it is subtle and other times there is no apparent connection whatever. Those cases usually arise as a folding accident or because I take time out from the challenge which is occupying me.

The Tomoko Twist Challange produced one creation which has an obvious connection to the challenge which spawned it and one which is more subtle.


We will start with the oblique triangle sided box shown here. It has obvious design similarities to the box of the last posting but the mode of construction is actually quite different.

The twist is on the floor of the box. The walls are held together by tucking the side tabs in between the wall sections. The top is covered by tucking the top tabs under the adjacent flap in a clockwise direction. The petals sandwich the flap between it and the tab underneath.

The crease pattern has some lines in muted tones. These are additional creases which may be added for thin paper or if you want the walls to be extra sturdy. They are generally not needed.

The Tomoko Twist Transformation Trials: 2

Here is a third lid for the American Letter sized Triangle Sided Twist Box. It has a small insert which matches the color of the base. The insert is made from a square sheet of paper with a width which is equal to two of the nine sections of the lid.

This lid and base confirmed that the best sizing for 20lb copy paper is American Legal size minus 1/8 inch for the base and standard American Legal size for the top. These two fit perfectly: not too tight, not too loose.


Here are the crease patterns for both parts.

CLEMENTE GIUSTO'S RECTANGULAR BOX

Clemente Giusto is a talented origami designer who has only recently been discovered hiding in an Italian town. Now his work is being shown and taught around the world. In the US, Yami Yamauchi has been promoting Giusto's sophisticated Rectangular Box.

Not only has Yami re-diagramed this work but he has made a die for scoring multiple sheets. With the crease pattern already on the paper even novice folders can learn to fold this model quickly and easily. You can see Yami demonstrating his method in Los Angeles.here.http://havepaperwilltravel.blogspot.com/2009/01/wcog-january-meeting.html


Thanks to John Andrisan, also from Los Angeles, I obtained a copy of the diagrams of this model which were drawn up by Paola Scaburri. This week I found time to try them out. The result was as charming as I expected.

I had one complaint. The internal triangular flaps did not support each other. Whichever of the flaps has been folded over first will fall into the box rather than sit on the underside of the roof.

I came up with a relatively simple solution to this problem. I added a crease half way down the triangular flap of one side and then inverted half the triangle to make a pocket. The point of the triangular flap from the other side can now sit inside this inversion and support its weight, which in turn, is supported by it.

For reasons which i hope will be apparent later, I also turned over the top left hand corner of the paper.




Some of the details on the Scaburri diagrams seem to be incorrect or less than optimum. It seems that the lateral valley folds that become the internal roof triangles should be mountain folds. There appears to be no good reason why they should be folded in the other direction first.

I have drawn up a crease pattern diagram incorporating these features and have added some photos for clarification. With the help of the video of Yami's folding method this should be sufficient for most folders to figure it all out.


The following photos are taken from several differently color models. I hope no-one is confused by this.






The creases which are shown in the top left hand corner of the CP pattern (see previous image) are not shown on this pre-creased sheet. I folded the corner over later in the procedure.











The walls are pulled up, the diagonals are reinforced and the corners are pinched together.


The tip of the large triangular flap is inserted into the triangular pocket on the other side. This becomes the lower roof of the box.


Next, the lateral sides are folded towards the center across the top of the box. They should want to do this naturally.

At this point you should have a rectangular box shape on the bottom and a couple of "wings" on the top with points which arise from pleats on the under sides.





The aqua blue model has the side flaps pulled back so that you can see how the layer with the pocket triangle looks. The side walls will naturally cover this.





The blue jeans model shows what the box looks like when the top layers are allowed to fall into place. The circle draws attention to the top left point which can be folded in half at this juncture.




















Fold up the flaps.





(Only one of the models shown has the top left corner point folded in half. When I put the others together I folded the flap over later in the procedure. You can choose to leave the creasing until it is necessary or you can pre-crease earlier. Note that the original model did NOT turn this point under.)





Fold the flaps over and tuck them under as shown. Fold in the order shown. In the demonstration photos the box has been turned part way around so that you can see the procedure more clearly.










Like the model with the hair pin holder, the next flap is left untucked in the original model. In my variation I turn over the corner (remember what I kept hinting at?) and tuck it under its contiguous strip. If you haven't creased this point before now, this is the time to do it.


















































































Now for the last flap.







You've finished. Enjoy your box.

BOUNCE BOX and TIER BOX

The past few days have been spent developing a modular hexagonal box which bounces and a related modular hexagonal box which stacks but does not bounce.

The two box types can be combined, in various combinations, to form a tier box which bounces. The combination model can even be connected near the base to form strings of boxes or hexagonal "circles" of tiered boxes.

The photo shows one way of connecting the sections. It is a photo of the rough proto-type models so don't look for perfection. Expect to see crumple, because it is certainly there! Designing a model generally results in a lot of messy models before the final version is reached. Unless you are Robert Lang, of course.

There are six sheets of paper used for each of the several sections.

Almost all of the starting sheets are half squares, that is, rectangles with a 2:1 ratio. The patterns can be printed onto paper via an ordinary computer printer. The limitation here is that the largest piece can be no taller than the length between the minimum printer margins at the top and bottom of a page. This translates to a box with a diameter of about 4½ inches.

The sections stack inside or around each other. Lids become bases to accommodate stems. Stems end in boxes which accommodate other boxes and/or lids.

There are two lid styles. One is an overlay style, the other fits flush with a base box but overlays an inlay box. One of the two lid styles is being used as the base for an extension tier in the photographed example while the other is on top of the model.

The box wobbles from the base. The wobble part is obscured in the photograph which was taken from the top to show the lid decoration.

It will be several days before all the problems of its construction are resolved at which point I will make it with a variety of colored papers which will better demonstrate the modular and the sectional construction. Then I will post the Crease Patterns for each model of each section.

There are several sections which are not shown in the photo. One inlay box style is still in design infancy. Two other inlay styles were stackers which were not photographed because there insufficient lids to accommodate them. Photos of these will be posted in blog postings to come.

This is a fun box which, nevertheless, has practical applications.
