I posted a photo of a test model of the downhill diagonal shift earlier this year. Here is the crease pattern for that model. The central part of the crease pattern is exactly the same as the standard uphill diagonal shift I’ve posted crease patterns of before. The top and bottom sections are the crimp-bends I recently posted and build on the sine waves used in the central diagonal shift. Since each portion of the crease pattern is a distortion of a tube, it’s fairly straightforward to stack these in all sorts of interesting combinations.
