This is a male human 1:1 scale brain. The data is from a mri-scan. I used slicer to convert the DICOM data to stl. Then I used blender and meshmixer for correction. Slicingsoftware was Cura. All softwares are freeware.

After printing the two parts,, i glued them together with superglue and paintet it. A M3 thread was manufactured at the spinal corde. The base was manufactured from aluminum.
