2-D Modular Design Process and Diagrams

Lately I’ve been playing with dollar bills and that translated into modulars which can be seen two posts down.  As of yesterday that translated into 2d modulars with a square.  I am the first to state there are tons of modulars out there and my designs are probably not very unique.  When I started doing origami I generally focused on 3d modulars, but I have taught three particular 2d modulars (One is called the “Magic Frisbee,” another is a Mette Pederson unit, and the final one is a stellated star that I learned from a origami day planner with a frog on the cover).  However this post is only about “steps” I have observed when I am designing modulars with dollar bills or squares.

 2-D Modular Design Process

  •  You have to have something that is either a pocket or an edge to but the next piece next to.
  • Determine if you can make it work around a single point.  The angles must come to approximately 360 degrees.  You can do this with math or (like I tend to do) just make the modules and assemble.
  • Determine the two angles the modules can shift in.  Depending on the angle of the pocket/edge from step one the angles are different.
  • Determine a way to keep the shifting from occuring by tucking somepiece into another piece.

I admit these are obvious steps, but once I verbalized them when trying to explain to my mother how I came up with things it has been easier to make things come together.

Edit:

Here are some dollar bill modulars.

After making a series of dollar bill modulars I applied the same approach to a square.  The results are two units I now I havn’t made.  However the end design of the three step module I have seen.  My standard request applies…If you have seen them please leave applicable designers and links so others can find them and we can all expand our knowledge.  I asked around at the CHAOS meeting today and no one recognized the modules, although Robert did say the end result was familiar on the three step modular. 

 

In the last step (which is what makes the modular fairly strong)  I bisected the paper from the tip, allowedthe bottom by the white edge to go down, and tucked the excess into the white Isosceles triangle.  If you want it to look like the pink design repeat on the other side.

Hexagonal Dollar Bill Modular Instructions

You will need 6 crisp dollar bills (or larger if you so wish) and a few fingers.

  1.  Fold dollar bill in half lengthwise.  I recommend keeping the same orientation I have the first time you make it.    
  2. On the one side quarter it.
  3. Fold in half, Valley fold, as shown in photo.
  4. Take the lower left vertex and bring it over to the quarter crease line.  The other point it references is the center crease line.  
  5. Inside reverse as shown.
  6. Use the upper left vertex and bring it down to the center crease mark making a crease the the other top vertex. Unfold
  7. Repeat on the left side and unfold.
  8. You are folding down as if to make a waterbomb base.
  9. Flip unit over and repeat.  When done reverse all creases so the “waterbomb” is in the inside.  Make 5 more units.  
  10. Put units together as shown.  You are putting the one on the right into the one on the left.
  11. Between the units where the units connect fold a bit of paper over.  This creates a strong final product.                    
  12. Assemble all 6 units.  Should look like the picture.  Then flip over for the next step.
  13. You are tucking in the left angled flap all the way around.  It goes around the other papers in the inside.  Now this side has only rotational symmetry not bilateral symmetry.
  14. Flip over.  Now you will be collapsing the modified waterbombs.  Be sure to include the tip from the other side that was left out.
  15. Now you are tucking in the tips that are sticking out so that everything is contained.  The final modular should be internally very strong.                                     

Moneyfolds: My design approach

Just a few thoughts on the process I’ve been using for moneyfolds lately.  Dollar Bill origami is a very recent foray of mine.  I have found the dimensions interesting from a design perspective.

My basic approaches:

  •  Not to be flippant, but I fold.  I take every angle and bisect, trisect, and intersect it in every way that I can think of. 
  • I try to collapse things in different ways from all different angles and sides.
  • Visualize what I want and deconstruct the folds in my mind(only works on rare occasions and never for highly complex stuff for me)
  • Once something bares a resemblence keep refining it till it is good enough.
  • Make more than one of something and see if they’ll hold together.

I have had mixed results with these approaches and I havn’t done much with animals (certainly none worth posting) but I do find it interesting to play with something that has limited symmetries.

Side bar… I have now had this sight for a full year.  Time flies when you are folding.

Dress Diagrams & Dollar Devil

The initial steps of this are a pain.  Reference points carefully. 

1.  Fold in half lengthwise.db1

2. Mountain fold as indicated.  The second pic shows the reference points on the dollar bill.

3.  Look at pic.  Line up the right side and make mirror folds.  Do it on the other side.

4.  You are making a valley fold that is the diameter of the circle.  Use reference points for alignment.  I’ve also drawn the line for reference.

5.  This is sort of similar to creating a waterbomb base.  The trick is some of the paper in the center overlaps and has to goto one side or another.  I highly recommend referencing the pictures for this step.

6.  Flip over. and valley fold betwee the two vertices.  The crease line is drawn on the bill.

7.  Flip over.  You are folding the vertical lengths to the center crease (folding quarters).  It should start resembling a dress/robe.

8. The tips that are sticking out above the shoulders are mountain folded to match the edge behind it.

9.  The arms are mountain folded on the line that between the white and green on the bill.

10.  This section is to taste.  I mountain fold the bill and then valley fold.  Reference pictures.

11.  Flip over.

12.  This makes the waist.  I recommend looking at the photos and trying to repeat.

13.  Flip over.  The tips by the hips need to be mountain folded to soften them.

14.  If you want you can end here. 

15.  To add detail fold back the edges of the dress.  See pic.

16.  To shorten dress  pleat internally to taste.  You can fold the tips at a 45 degree angle for more detail.
