Matryoshka chicken/egg

I always have find interesting the Matryoshka dolls and the chicken or the egg dilemma(If you don't know what is this i will put abrief decription of them below). And I came up with the idea of combining them for the tinkercad and myminifactory Easter challenge.

Scaling up or down the files you can make more 'dolls', and you can chose, acording to your opinion with the dilemma, with wich on you want to start the egg or the chicken. I made the three first dolls with the two versions, if you want you can make more.

A set of matryoshkas consists of a wooden figure which separates, top from bottom, to reveal a smaller figure of the same sort inside, which has, in turn, another figure inside of it, and so on.

The chicken or the egg causality dilemma is commonly stated as "which came first: the chicken or the egg?". The dilemma stems from the observation that all chickens hatch from eggs and all chicken eggs are laid by chickens. "Chicken-and-egg" is a metaphoric adjective describing situations where it is not clear which of two events should be considered the cause and which should be considered the effect, or to express a scenario of infinite regress.
