3D Brain Puzzle

This is my brain made into a 3d puzzle. I struggled to cut it properly to make the pieces fit, but I think it ended up well. I used magnetic bands to make sure the pieces stick to each other when you get them close.
It's been a few years since I made this, but recently, someone asked for the design for their own, so I thought I'd share it here.

The temporal lobe was quite hard to chop into pieces bc it has many components. There are two versions for the right hemisphere. I would recommend printing both so that you have all the pieces. I don't remember why I re-cut the pieces for v3. You can find out and tell me!
