Hyper Nova

Turn twelve squiggly starfish cut-outs into an amazing twelve pointed star where each point is ten-sided and starfish arms are interlocking.

Step 2

Cut out the twelve parts by cutting on all black lines.  On all twelve parts, fold the green lines at the glue flaps as valley folds.  

STEP 3

Connect Parts 1, 2,  and 3.  Note that the glue flaps in this project are each labelled with a number plus the letter A or B.  The number is the number of the point being formed, so all glue flaps at a point should have the same number.  Also, A flaps are always glued to a B flaps.  For this step, glue the following flaps to each other:

  Part 2 Flap 1A to Part 3 Flap 1B

  Part 1 Flap 2B to Part 3 Flap 2A

  Part 2 Flap 3B to Part 1 Flap 3A

  Part 1 Flap 6B to Part 2 Flap 6A

  Part 3 Flap 4B to Part 1 Flap 4A

  Part 2 Flap 8B to Part 3 Flap 8A

Step 4

Add Parts 4, 5, and 6 to the project.

Add Part 4 by gluing the following glue flaps together:

  Part 4 Flap 1B to Part 3 Flap 1A

  Part 4 Flap 3A to Part 1 Flap 3B

  Part 4 Flap 9A to Part 3 Flap 9B

  Part 4 Flap 5B to Part 1 Flap 5A

Add Part 5 by gluing the following glue flaps together:

  Part 5 Flap 1B to Part 4 Flap 1A

  Part 5 Flap 4A to Part 1 Flap 4B

  Part 5 Flap 10A to Part 4 Flap 10B

  Part 5 Flap 6B to Part 1 Flap 6A

Add Part 6 by gluing the following glue flaps together:

  Part 6 Flap 1B to Part 5 Flap 1A

  Part 6 Flap 1A to Part 2 Flap 1B

  Part 6 Flap 5A to Part 1 Flap 5B

  Part 6 Flap 2B to Part 1 Flap 2A

  Part 6 Flap 7B to Part 2 Flap 7A

  Part 6 Flap 11A to Part 5 Flap 11B

Step 5

Add Parts 7, 8, and 9 to the project.

Add Part 7 by gluing the following glue flaps together:

  Part 7 Flap 8B to Part 2 Flap 8A

  Part 7 Flap 2B to Part 6 Flap 2A

  Part 7 Flap 6A to Part 2 Flap 6B

  Part 7 Flap 11A to Part 6 Flap 11B

Add Part 8 by gluing the following glue flaps together:

  Part 8 Flap 2B to Part 7 Flap 2A

  Part 8 Flap 2A to Part 3 Flap 2B

  Part 8 Flap 7A to Part 2 Flap 7B

  Part 8 Flap 9B to Part 3 Flap 9A

  Part 8 Flap 3B to Part 2 Flap 3A

  Part 8 Flap 12A to Part 7 Flap 12B

Add Part 9 by gluing the following glue flaps together:

  Part 9 Flap 3A to Part 4 Flap 3B

  Part 9 Flap 3B to Part 8 Flap 3A

  Part 9 Flap 4B to Part 3 Flap 4A

  Part 9 Flap 10B to Part 4 Flap 10A

  Part 9 Flap 8A to Part 3 Flap 8B

  Part 9 Flap 12A to Part 8 Flap 12B

Step 6

Finally, add Parts 10, 11, and 12 to the project.

Add Part 10 by gluing the following glue flaps together:

  Part 10 Flap 4A to Part 5 Flap 4B

  Part 10 Flap 4B to Part 9 Flap 4A

Part 10 Flap 5B to Part 4 Flap 5A

  Part 10 Flap 11B to Part 5 Flap 11A

  Part 10 Flap 9A to Part 4 Flap 9B

  Part 10 Flap 12A to Part 9 Flap 12B

Add Part 11 by gluing the following glue flaps together:

  Part 11 Flap 5A to Part 6 Flap 5B

  Part 11 Flap 5B to Part 10 Flap 5A

  Part 11 Flap 6A to Part 7 Flap 6B

  Part 11 Flap 6B to Part 5 Flap 6A

  Part 11 Flap 10A to Part 5 Flap 10B

  Part 11 Flap 7B to Part 6 Flap 7A

  Part 11 Flap 12A to Part 10 Flap 12B

  Part 11 Flap 12B to Part 7 Flap 12A

Thread Part 12 through an opening to maneuver into place, then attach by gluing the following glue flaps together:

  Part 12 Flap 8A to Part 9 Flap 8B

  Part 12 Flap 8B to Part 7 Flap 8A

  Part 12 Flap 7A to Part 8 Flap 7B

  Part 12 Flap 7B to Part 11 Flap 7A

  Part 12 Flap 11A to Part 7 Flap 11B

  Part 12 Flap 11B to Part 10 Flap 11A

  Part 12 Flap 10A to Part 11 Flap 10B

  Part 12 Flap 10B to Part 9 Flap 10A

  Part 12 Flap 9A to Part 10 Flap 9B

  Part 12 Flap 9B to Part 8 Flap 9A

A fabulous way to build a dodecahedron star.
