Please help me identify the underlying shape

Plugin: It uses Pufferfish to get the twisted boxes between surfaces

I thought it was a single layer morphed box between surfaces filled with gyroid unit shell, but it seems not.
Do you have any idea what shape this is?

It Kinda reminds me of shapes in this video, with addition of minimal surface and mirror cut mesh.

Spatial Synthesis V1.0

Maybe something like this for single half module:

Then mirror, smooth naked edges then kangaroo minimal surface. The mirror cut mesh and rotate

But thats probably not it

Thanks for your reply. I tried the geometry shape you showed, and experimented with various methods to replicate the form in my reference image, but I couldn’t get it right. I think your approach is correct, yet I still can’t figure out the base underlying geometry.

[Edr (Eddard)]

Original image is very hard to read. But those light spots seems to be holes so maybe original topology is closer to such shape

Also if going in periodic mesh direction MeshPlus plugin has few more examples.
Maybe Batwing Mesh is kinda worth studying.

Yes, that is the thing that dawned on me today, and I am actually trying with the components in the Mesh+ now.

And by now my guess is this guy - Nevious.

I think the vertical row of twisted boxes is the usual TPS cells, but the next side colums of twisted boxes is a mirrored version of it.
Lastly, the final shape was cut with a simple ovaloid/egg surface.

Using isopod + cutting shape would be a good test.

Hmm, my try here…
But how to get more precise control of openings in TPMS field?
