Apple (Shuzo Fujimoto)

I fear they're out of print. If you're a member of the British Origami Society, they have copies in their library that include the diagrams. Here's all the sources where the diagrams should be published:

BOS Convention 1982 Autumn
BOS Magazine 102 October 1983
Origami per Pinocchio by Roberto Morassi

But there is hope still. I have permission from Fujimoto-san to make a video of this model, and I plan to do so some time in the future. It's not all that hard to fold, so maybe within the next 6 months?

Hope this helps a bit,

I plan to make a video on this, especially because diagrams are *very* hard to come by for this. I've got permission, so all I need is ... find some time to make that video. It'll probably happen in the next 4 months or so.

It's not really a tessellation, and definitely different than all the three models you mentioned. For one, those are on a square grid, while this apple uses a triangle grid. And there is no collapse step that's even remotely like the ones for the (true) tessellations you mentioned. While the apple has some tessellation aspects to it, I'm somewhat reluctant to call it a tessellation (although Shuzo Fujimoto seems to have titled it a tessellation apple).

You can make a closed bottom by adding some extra creases. In essence, just do exactly the same as for the top. It's a bit trickier, though, and I'm not sure I really like that result much better.
