An icosahedron is a regular polyhedron with 20 identical
equilateral triangular faces, 30 edges and 12 vertices. It is one of the
five Platonic solids.

Reference: Ployhedron Origami for Beginners - Miyuki Kawamura

No of units: 12 units (Blue for vertices) + 30 units (Yellow for edges)

Paper size used : 3" x 3"

Paper used: normal color printer paper

Time: around 2 hours to make the units and assembling

Note: I found it little unstable while assembling. The joints came apart while assembling new ones. I realized this is where Origami tests our patience. Finally very reluctantly I used glue, just to complete the model.

There was dodecahedron too in the book, I didn't try it.

This is the end of platonic solids frame type.

I will be posting more of intersecting planes, very interesting and very beautiful models. I have finished up to 8 intersecting planes starting from 3 (XYZ co-ordinates). As we go up units are more, need to spend more time cutting and folding individual units. Look forward for intersecting planes family on my blog.
