Ninth Stellation of the Icosahedron
This model is made of 12 pentagonal pyramids and uses 5 different colors. Each pyramid will contain one of each of the 5 colors. You will need to use the template below to make 12 pieces of each color.
In his book, Polyhedron Models, Father Wenninger gives this description of the pyramids that you must make;
(1) Y B O R G
(2) B Y R O G
(3) O B G R Y
(4) R O Y G B
(5) G R B Y O
(6) Y G O B R
Create a pyramid with the colors of (1) ... Y B O R G.
You must be consistent in how you order the colors in your pyramid! All of your pyramid faces in this first half of the polyhedron must be arranged in the same clockwise or counter-clockwise direction as you glue them together.
I have arranged my 5 faces in a counter-clockwise manner as they were viewed from the top of the pyramid. It will be necessary to severely trim the tabs of your pyramids near their peaks in order to not have bunched material interfering with your star's point.
On the right-hand tab of the first face (in this first case, the yellow face) mark the number of this pyramid ... in this case # 1.
Create your first 6 pyramids in this manner. Glue the faces together in a counter-clockwise arrangement and number each finished pyramid on the right tab of the first color.
Now arrange pyramids #2 through #6 in a counter-clockwise manner (according to their numbers) around pyramid #1. You will be gluing the left-hand tab of the first face in pyramid #2 to the numbered tab of pyramid #1. Then you will glue the left-hand tab of the first face of pyramid #3 to the right-hand tab of the second face in pyramid # 1. Continue in this manner ... left-hand tab of pyramid #4's first face to the right-hand tab of next face in pyramid #1.
You should now start to see part of the 3-pointed stars that will share the same facial plane and have the same color.
