Does anyone know if this model is diagrammed anywhere and if so where?
And please don't give me the "Gilad Aharoni's page or origamidatabase.com have lots of information on where models are diagrammed" because I already searched there without luck.
On page 15 of this PDF file (from the workshop on Origami-Based Modeling and Analysis held in 2016) there is an abstract by J. Maekawa titled "Cube division – old and new artistic exercise": http://cmma.mims.meiji.ac.jp/eng/pdf/IC ... abst_w.pdf
There you'll find a CP of "Cube with a hyperbolic paraboloid" and a reference to Maekawa's book “Oru Kikagaku (Folding Geometry)”, Nippon Hyoron Sha, 2016. More info on the book: https://viereck-verlag.de/en/produkt/fo ... eometry-2/
