The old Greek puzzle how to double the volume of a
given cube
Model and Diagram by Thoki Yenn
I decided it was easier to go
the opposite way, folding a cube
with half the volume of a given cube.
And for fun fold the other half volume
as a trihedral wall from a square
the size of the original Square.
The folding instructions for the
TRI-HEDRAL WALL are not yet
available, but have go at it anyway.
Have a look at the preparation of the
Creasepattern
Have fun.
