A hinged dissection of an octagon to a square. Inspiration from "Hinged Dissections: Swinging & Twisting" by Greg Frederickson (p120, Figs. 189a, 189b).

This model requires some metal pins to assemble. I made the pins from common roofing nails (18 gauge or 0.122" diameter). Details shown in this video: https://youtu.be/Ma3mqF_yVuI
