Origami decahedron

@ivan-g has recently posted the instructions to make an open cube origami that can be linked together into a chain

Using the same unit you can make an origami decahedron following these instructions.

Begin by folding twelve units.
This unit can point to the left or the right my unit points to the left @ivan-g points to the right as long as all twelves units face the same direction it doesn't make a difference when constructing.

Assembly of the cube is as follows:

Assembly of the decahedron follows this path:

Adding the next three:

For the next three pieces use a different colour as it can be easy to lose track of where you are up to.

Add the last three units in the same way to complete the decahedron.
