Starry Night

See the stars of the Milky Way every night (and every day) with this Starry Night 3D paper craft.

Step 2

Cut out the thirty identical pattern pieces by cutting on all black lines.

STEP 3

On all thirty parts, fold the green lines as valley folds, and then glue together the two long glue flaps.

Step 4

Connect three parts.  Connect the first and second parts together with one glue flap.  Connect the third part with a glue flap to each of the first and second parts to form an open triangle. 

Step 5

Add six more parts by connecting a new part to each of the six glue flaps on the module completed in Step 4.  Connect together each pair of new parts with a glue flap to form an open triangle at each intersection.   

Step 6

Add three more parts by connecting a new part between each pair of parts added in Step 5 using one glue flap on each side of each new part.  The first three open five–pointed stars will now be formed.

Step 7

Add six more parts, each attached with two glue flaps to two adjacent flaps on the project.  Adding these parts will complete six more open triangles.  

Step 8

Connect three more parts.  Add each between a pair of parts added in Step 7 with one glue flap on each side of the added part.  This will complete three more open five-pointed stars.  Then add six more parts with one glue flap each to the project; and then use another glue flap to connect each pair of these new parts to form three more open five-pointed stars.  

Step 9

Connect the last three parts to the project using two glue flaps on each.  Connect these last three parts to each other with the remaining glue flaps. 

This Starry Night has twelve open 5-point stars, thirty open 4-point stars, and twenty open triangles. Do you see the rhombicosidodecahedron?
