Threaded dragon egg nesting dolls - Easter decorations

I happened to find itTony YoungbloodI saw the "screw-shaped dragon egg" and thought, why not make a nesting doll?

So I tried and found the appropriate scaling ratio.

Yes, I did it in Excel 🤓

So this means that on a typical Bambu Lab printer, such as the A1/X1/P1, with a build volume of up to 256mm in width and height, you can print at least five iterations.
Unfortunately, I can only print the first three iterations, but I should be able to adjust the tolerances and other parameters.
It's really cool that the first egg is 100%, and the third one is 200%

Two 100% eggs can also be placed in a 200% egg.
The Excel spreadsheet is attached.

Have a pleasant time printing and making things by hand.

Printing instructions:
The first printing plate includes three versions of eggs, each of which is 100%, 142%, and 200% the size of an egg. The others all have names. Due to their large size, the final shells are printed separately, so the third plate contains 282%

If the egg doesn't fit perfectly, try printing it at a larger size or rotating the egg. The screws will align, but they'll be quite tight:
