Primate Brain - MRI

This is courtesy of amyo on the OpenSCAD forums.
It is a representation of a primate brain from MRI scans.
This STL has been cleaned and is manifold, and usable as an import() to OpenSCAD.
It is a LARGE STL.
Also inclused are two negative halves intended to form a mold. These may print best if rotated, depending on the capability of your printer.
I have not printed this.
Update: Added the brain split into two halves for printing. Probably needs support.
