Cube Model, Pedagogically Stretched

####Cube Model, Pedagogically Stretched

**Update**: Trimmed the inner edge end a bit more to allow "easy insert".

There is a great deal of mathematics around and within a cube. The present design allows students to make their own models and then play around and within the cube for mathematical insight, especially the triangles and angles. The Pythagorean Theorem will come in handy in many cases!

To play with the mathematical ideas, one needs a long elastic cord such as those for name badges (with some hard end covers), 8 vertices, and 12 edges.

To assemble the cube, feel free to press the vertices against some hard surface or use a pair of pliers. Once assembled, it may be hard to take things apart. If so desired, please use the loose vertex or increase the printing resolution.
