I think this Spike Ball is really cute. It reminds me of a bunch of “cootie catchers” all stuck together.

This interesting project was initially designed by Rona Gukewitz and Bennett Arnstein in 1996 in 3D Geometric Origami: Modular Polyhedra by Dover Publications.

Project Steps

Getting Started

You will need 12 pieces of Origami paper. I used 3×3 paper – but you can use whatever size you wish.

Origami Spike Ball Step 1

Fold a + in the paper. Starting with the color side down.

Step 2

Turn the paper over so the color is showing.

Origami Spike Ball Step 2

Fold edge to the center on both sides.

Origami Spike Ball Step 2

Do the same on the other side.

Step 3

Turn over to color side down

Fold each point to the center.

Step 4

Turn over to color side up.

The next few steps should pop right into place. Fold up the right side and push just the center down.

Do the same for the bottom. You will see a little square emerge in the corner.

Step 5

It will look like this after all sides are pushed in.

Turn the paper over.

Fold the point to the center – but be careful and let the underneath pop out.

Step 6

It should look like this after all 4 sides are folded in.

Origami Spike Ball Step 6

Turn over.

Origami Spike Ball Step 6

Turn back over so color side is down. Fold corner to corner – in both directions. This will be a bit hard – there is alot of paper. Just take your time.

Step 7

Hold on to each side and push in toward center. This reminded me of a cootie catcher.

Carefully pop out each flap.

Step 8

Make 11 more!

Step 9

Now lets put it together!

Origami Spike Ball Step 9

Place two units next to each other.

It doesn’t matter which side goes on top. Pick one and slide it into the other unit.

Step 10

Origami Spike Ball Step 9

Origami Spike Ball Step 10

Take your 3rd piece and connect the triangle. It will get a bit tight trying to slide each piece in. Just work slowly.

Step 11

Origami Spike Ball Step 11

Origami Spike Ball Step 11

You just made a triangle so this time we are going to make a square. The pattern just goes back and forth. You will use 2 units to make a square.

Origami Spike Ball Step 11

Continue this pattern all the way around.

Step 12

The last few pieces are pretty hard to get in. Sometime they don’t want to slide in easily. I usually try a different side, sometimes that works.
Have fun making a cute Spike Ball! Happy Folding!
