## Recycling Symbol

A modular recycling symbol, my design from 2021. Mathematically speaking, it is a Möbius strip. Folded from three units, each forming one corner of the trian...

These are modular origami models which create a one-dimensional structure (as opposed to quilts, which are two-dimensional). Such models can usually be extended to arbitrarily large numbers of units. By connecting the two ends, a chain can be transformed into a closed ring, but structurally I treat this as just a variant of the same model.

I haven’t seen any specific name used for such structures so far, so I introduced my own, *origami chains*.

This page lists **models** of a single type. You might be interested in folding instructions instead.

Each link of this chain is a Möbius strip folded from a single CBU unit, essentially a Möbius Strip V (CBU). For a chain with regular, round links, see Chain...

This Möbius strip is made from a single Conveyor Belt Unit (CBU), just like Möbius Strip V, but the ends are twisted additional 360° before being connected. ...

A Möbius strip consisting of a single Conveyor Belt Unit (CBU) twisted and locked with itself by both ends. This is the cleanest representation of a Möbius s...

A conveyor belt, made from Conveyor Belt Units (CBU). Instead of connecting the ends together, one could also leave the model in the form of a flat tape, or ...

When I was little, it was common for kids to make paper chains as Christmas tree decoration (łańcuch na choinkę). These chains were made by cutting colored p...

This is a model I designed and folded back in 2016. It is made from the same kind of units as Single-Module Modular Heart. Any number of units can be used si...

A Greek meander pattern folded as modular origami. The bent frame technique is the “Thoki Yenn style” which I also employed in a number of other models, for ...

The Möbius band (aka Möbius strip) is an interesting mathematical object, a single-sided surface. This origami version is folded using my Cross Lap Unit (CLU...

A single-sided surface, the Möbius Band is one of the more interesting mathematical objects that can be reproduced in origami.

This ring can also be worn as a headband. It uses a non-standard way of connecting the modules. Any even number of modules can be connected this way, though ...

This is one of the rather few modular origami designs which use an odd number of units. Compare also with another similar model.
