This started as a 20"square, divided into 32 divisions. Conventional box pleating, and the final model has a 10x10" "framed area" with a one division border all around so the model will fit nicely under a 10" mat. Each of the small boxes are traditional masu boxes, and the center box has an aspect ratio of 1-grid wall to a 4 grid base. Eight of these (with a slightly different "ninth" center panel) would make a stage 3 version. With best wishes, Galen T. Pickett https://www.etsy.com/shop/GeometricOrigami
