Today I'll introduce you a spring with telescope function. You can stretch and squeeze it.
There is an octagonal version of this model by 'oschene' (he is in my followers list) and I wondered if it's possible to make a variation of this model (pentagonal or n-gonal). And yes everything is possible if you don't give up.
The CP is simple to understand, it repeats the same pattern again and again. The only difference is the reversed folding process (mountain folds instead of valley folds and the opposite) between spring structure and frame.

The steps are very similar to my last instructables ('How to fold a Polygon', 'Pentagonal Antiprism Lampshade'). 
So let's get started.


Step 1: Preparations

You print out the crease pattern fullsized (attachment below) and bring it to the right format (cut the black borders off).
Then you precrease and prefold everything like shown in the cp.

-Blue is mountainfold
-Red is valleyfold

Step 2:

The glueing area is marked on the right side of the CP as dotted lines.
Glue and form the prefolded paper into a high tower.
 

Step 3:

At first you begin with the frames on both sides.
Please visit my last instructable (Pentagonal Antiprism Lampshade) to find out how to fold frame. 

Step 4:

To fold the mechanical spring you begin from outside to inside (middle).
You need both hands to fold from both sides simultaniously and you reach the center of the spring. It's a folding and twisting in opposing directions.

Step 5: The Result

As result you'll get a spring that can be stretched in 7 steps like a telescope antenna.
Good Luck and Happy Folding!

Well, a few more explanations would be really helpful. As for example wether to put the drawn lines of the crease pattern outside or inside when glueing together... Such simple information would really make it easier to understand...

by studying and gaining experience. When I study the folding patterns, it's like reading between the lines.

This was fun to make, although through trial and error I ended up throwing the first couple away. You say that it is easy to port this to a n-agonal shape. How? You mentioned 'oschene' for an eight sided. and you have what looks to be like a 20 sided in your picture, what is the folding pattern for these?

It's an 18-sided spring on the left side. In my another instructable I gave a hint, how to modify the number of the polygons:

Second all the comments. Just cleaver and neat. My granddaughter left a pile of paper balls on the floor in her impatience. I too would like to know how you would design and 8 or n sided bellows? There must be some math involved here but my geometry is many years hence.

Raise your hand if you balled yours up and threw it in the garbage because you couldn't get the folds right...

Put an LED bulb in there (so there's no heat and no fire hazard) and you'll have a lamp.
You could even use black and white printed images on the paper before you fold it.

"Origami Spring" would be a good band name.

I think this has practical applications if made in plastic with cut hinges instead of paper and folds. The hinges could be easily cut with CNC or even just die stamped in production. It would certainly make a good replacement for various type of "boots" that fit over this or that piece of moving machinery. It could also replace some types of air hoses. By cutting the hinges asymmetrically, you could probably make it bend and arch in a very specific pattern which could be very useful. 

If you made it from a laminate of a rigid exterior with a springy and flexible interior, you could make a very large and powerful plastic spring. That would have a LOT of applications. 

Keep folding.
