Origami Press - Miura Fold

thingiverse

The goal of our Origami Press is to enable us to pre-crease more challenging designs, such as the [Miura fold](https://en.wikipedia.org/wiki/Miura_fold). The Miura fold is a "map fold" consisting of a partially-angled grid that can fold into a small square and open up into a large sheet in one fluid motion. Thes type of folds are famously used to make [expanding solar panels](https://www.nasa.gov/jpl/news/origami-style-solar-power-20140814) on space satellites and [wallet-sized collapsing city maps](http://www.bun-sho-do.co.jp/english/nextg/miura-fold/). Miura-type folds can be challenging to fold well by hand, for many reasons: the angles are hard to make consistently, it's difficult to fold through many layers of paper accurately, and the mountains and valleys alternate in such way that is difficult to produce without first creasing them the wrong direction. Our press allows us to pre-crease the folds so that they can be folded the rest of the way individually, at exact angles (84 and 96 degrees), and in the correct direction.
