I'm sure someone will come up with a better design, but until then, this is my version.

I used this as fetus but there's other options available, even aliens.

Build your own pod to grow your fetus.
This was inspired from the movie #the Pod Generation.
Pod was printed in PETG as have better translucent properties Light colors work best, but i do prefer the purple to the green. (too bright). Base was printed in PLA Matte.
All in 0.2 resolution and some parts need supports.
