Plaited Origami Polyhedra
Stage: Challenge Level: 
Some plaited polyhedral models appeared in and around the
Centre for Mathematical Science here in Cambridge, where NRICH
is based.
I was intrigued by how they were made and have taken some time
to work out the individual units the models are made
from.
Here are some pictures of the models. With the first few I have
included one image with the a basic unit partially visible so
you can get a feel for how the model was put together. At the
end of this article I have included images showing how the two
basic units that you plait together to make up these models are
made.
How to fold the basic units that make up the
polyuhedra:
Both start with a square:
