[Kamikaze]

If you want to create as close to a full pyramid whit most functions, the parts and things will need to be tiny... How small can you really make the water passages etc? What I've seen your small model is small but when looking at the whole construction in that size it's still quite large.
To big to move around.

Would a half meter high pyramid or such be possible? You could pay out and get the parts machined etc if you could get the details on how to construct it.

I do wonder how much a block of stone or several blocks. would cost to get manufactured into say such a half meter high model or such whit same materials the pyramid is actually made from. Though you would need many details and measurements needed to be made.
the parts would need to be high accuracy machined also.

But there are some questions if all the parts are there to get a rough working pyramid. Or are essential parts gone?
But just as is getting that shock wave water inside the queens and kings camber would be interesting... But there is a questions about the pathways and other things in the queens chamber that suggest something different was going on there than just water if it at all would have entered inside. Most peculiar are the two small passage ways whit their metal rods "doors" handles.
We would need to "explore" further to see what more can be behind there. The metal rods aren't there randomly and I think they would have been connected to something. The rods were severely corroded I remember, one being + the other - .
I remember reading someone suggesting what the queens chamber might have had for stuff inside those two passages behind the walls. There had been some kind of "effect" going on.
