Which is pretty much exactly the same as the previous model, the 8-Sided Compass Rose Jar. The difference is that this one is made from American letter paper (and it could be any size rectangle, really) and that instead of using that ?2/2 section to make the closure, this one repeats that section over and over, until it makes eight helical spirals up the sides.
Well, it more suggests eight helical spirals than actually creates them. Try it out, you’ll see. This is just the CP, but if you’ve successfully folded the 8-Sided model, you’ll be able to puzzle this one out pretty quickly.
I’ll hasten to add that this model squirms uneasily beneath the heel of the conceptual tyranny of 22½°-45°-90° angles.
Drawing this CP put me very much in mind of the Tholian Web episode of Star Trek.
