About this 3D model

I was bored during the pandemic so I decided to help out a friend with her thesis project. Smthg about dolphins brains, so i did a bit of research and found an MRI from a dolphin (dont remember from where), and used a software (follow this https://youtu.be/MKLWzD0PiIc tutorial) to turn it into an STL. It prints decent enough. Don't know if its accurate 1:1 size tho. The MRI *might* have been from here https://zenodo.org/records/44853 . Bottlenose dolphin
