QRSTUVWXYZ - 10 intersecting planes - Stars

Started on 21 May finished on 24th May 2013

After completing 9 intersecting planes I didn't start off with this one. It had become rather monotonous doing just the intersecting planes. I did a couple of curler models before starting this.

There is no color schematic diagram for this in the book. It is just mentioned that it should be assembled in truncated icosahedron pattern. I learnt that truncated icosahedron is just like a soccer ball, has hexagons and pentagons. Pentagons are surrounded by hexagons on all its sides. Hexagons are surrounded  by pentagons and hexagons alternatively.

Paper used: Color printer paper. Personally I find printer papers very comfortable to do Origami (I have tried Origami papers available in stores but I felt this is better). To make an individual unit there are two folds in the flap. For the initial units I had trouble.

Number of units: 10 x 9 = 90 , 10 planes 9 units each.

90 units

For any intersecting plane after making units and before assembling I arranged them in a plane like this. For 10 intersecting plane each plane is a Nonagan, polygon with 9 faces.

10 Nonaganal planes
Size of Paper : 4 " x 4 "

Difficulty : Moderate

Time taken : 8 hours roughly

Base Angle: 360 / 9 = 40 degrees

Reference:  Ornamental Origami: Exploring 3D Geometric Designs and link in David Petty (http://www.davidpetty.me.uk/ / Diagrams (on left side) / Clickable list of all models on this site / search for the diagram)

Also I referred to this photo to assemble initially (http://gurmeet.net/origami/qrstuvwxyz-by-meenakshi-mukerji/). Once I got all color units it was straight forward, I just followed the rule of truncated icosahedron and that same color papers should lie in same plane.

Half way - semi circle
Above pic: Half way assembly. One of the planes Dark Yellow is complete. There are 4 units remaining in each of the remaining 9 colors


Inspiration to try all the Intersecting planes:
  1. http://gurmeet.net/origami/ -- This site has instructions to many Origami models, it led me to David Petty's Origami Emporium site.  
  2. Ornamental Origami: Exploring 3D Geometric Designs and
  3. http://www.davidpetty.me.uk

All the above book and links helped me a great deal!! 

Here I stop intersecting planes. May be I will try Rectangular or other pattern sometime later.
