this is an instructable on how to make a stellated octahedron.
For those who don't know what stellated means it has triangles forming points from the segments.
there is also sekeletal octahedron. I didn't want to make them separate because I use the skeletal octahedron as the backbone of the stellated one
Step 1: Making the Units
Picture 2: Start with a peice of duct tape three times longer than how wide it is.
Picture 3: Fold a right triangle in.
Picture 4: Fold a right triangle above that.
Picture 5: Fold another right triangle in above that.
There sould be a sticky part left over.
Picture 6: stick one end to the other
Picure 7: Make 7 more.
Step 2: Assembly
Picture 1: What you should have.
Picture 2: Put tape on so a triangle sticks out.
Picture 3: using the tape, stick two modules together.
Pictures 4+5: repeat 2+3.
I forgot to take a picture of the next step, but repeat 2+3 again and tape the ends together.
Picture 6: Make another.
If you want to make it sturdy, or want to make a similar shape do the next step. if not skip them.
Step 3: OPTIONAL
Basically make another 8 modules, and tape them with the points in.
Step 4: Assembly Step 2
Now that that's done...
Picture 1: what you should have.
Picture 2: put tape on one side, like you did with assembling the previous ones.
If you made the skeletal octahedron, put it in now.
Picture 3 put the two sides together on the piece of tape you put on in picture 2
continue putting tape on the other sides
