Fractal Pyramid with Continuous Cross-section

Printed the 5-version for a girl interested in math. Perfect!!
Some interesting math facts behind this pyramid. If you look carefully, the pyramid consists of 6 small pyramids that are exactly the same as the big one. So if the big pyramid's volume is 1, then each small one's volume is 1/6.
On the other hand, each small pyramid is exactly 1/2 of the length, width and height of the original one. Therefore, a small pyramid's volume should be 1/2 x 1/2 x 1/2 = 1/8.
So 1/6 = 1/8?! It's a contradiction in your palm!!
0 (doesn't matter)
Must do .1mm height. Must do spiral outer contour (vase mode). Choose 0 bottom layer and 1 wall.
