Modular Origami: Icosahedron, Octahedron & Cube

Nov 28, 2011 02:32 AM

I spent the holiday weekend becoming fluent in the basics of modular origami. With practice, you can churn out the below models surprisingly quickly.

Icosahedron, Octahedron & Cube

My first attempt at the octahedron can be seen here, which I found was actually a bit tougher to finagle (in terms of assembly) than the the somewhat more impressive looking icosahedron (shown below). I found Math Craft admin Cory Poole's modular origami instructions for the cube, octahedron and icosahedron easy to follow, with the exception of the assembly of the octahedron, which I eventually pieced together through trial and error (and by cross-referencing this diagram).

I went on to attempt the Pentakis Dodecahedron with Cory's instructions, but couldn't figure out the sonobe unit modification, so I will use the notorious barbabellaatje of YouTube's video demonstration, and will be posting my results soon!
