Hi all, I've been trying to fold the star spring (hexagon-type spring) from Fujimoto as pictured in Invitation to Creative Origami, and I can't seem to work out the starting proportions. The Japanese text has the words "B4" and "B12" above the picture, but after consulting references for the ratios and cutting that size, it still doesn't match up properly.
There's a version that starts with a square in La Era Nueva (I think), but that looks like it's divided up into an 11x11 grid, and I'm not sure how to tackle that. Appreciate any ratio or h/w that you know that will help make this beast. I have actually gotten to the point (with paper running out on the end) where I can make the folds, so I'm looking forward to completing the model!
