Folding Origami Flasher Hexagon with Living Hinges
Description
<h2>Description</h2> This is a 3D-printable flasher pattern based on the work of Shannon Zirbel, Robert Lang, and several others. It demonstrates the ability of the flasher pattern to go from a flat state to a much more compact, folded state, all while moving with a single degree of freedom. <h2>Print Instructions</h2> This model is best printed in PLA, or some other similarly flexible material. <b><i>The model, at its current scaling, is intended to be printed with two 0.1mm layers as the base.</i></b> This ensures that all folds have something close to two orthogonal layers of filement on which to bend (printing with a single 0.2mm thick bottom layer will mean that at least two of the hinges will break very easily. See [this post](https://www.hubs.com/knowledge-base/how-design-living-hinges-3d-printing/) for a tutorial on how to make your own living hinges). [Here](https://help.prusa3d.com/article/modifiers_1767?_gl=1*1cosclm*_ga*NDM1MzMzMTEuMTY5MDMyMjcyNw..*_ga_3HK7B7RT5V*MTY5MDM5MTY5MS40LjAuMTY5MDM5MTY5MS4wLjAuMA..#_ga=2.31257535.1018801412.1690322727-43533311.1690322727) is a tutorial on how to modify individual layer heights in the Prusa slicer. It's best to remove your print from the build plate sooner rather than later: the residual heat from the plate will help you bend the creases into the model (see [this video](https://youtu.be/ERWortxlXKc) for which directions to bend them in). You're welcome to experiment with printing the first two layers out of a more flexible material, and then printing the remaining layers with something stiffer. PLA worked fine for the three demos we made. <h2>Alternative</h2> If you find that whatever filament you have is struggling with the default model, the rigid foldable alternative may be a good choice. It includes special bisections on certain panels, allowing for a folding action that doesn't place any transverse stresses on the hinges: its deployment only involves motion about the axes. The only trade-off is that it doesn't quite have the pop that the default model has in the opening and closing sequences. <h2>Sources</h2> If you want to study the math behind the model, [here's the literature it was based on](https://asmedigitalcollection.asme.org/mechanicaldesign/article/135/11/111005/693901/Accommodating-Thickness-in-Origami-Based). Robert Lang developed a program for Mathematica based on that paper, which was what we used to obtain the geometry for this model. A download for his program, Tessellatica, is available [here](https://langorigami.com/article/tessellatica/).
