Brain Puzzle

Brains are complicated. See if you can figure this one out.

The puzzle is based on a 20 sided icosahedron. Each edge has holes for a pair of 3mm x 3mm cylindrical magnets to hold it all together.

The files are grouped in to "Frontal," "Frontal Edge," "Cerebellar," and "Cerebellar Edge." Each group contains five puzzle pieces. Pieces labeled "Frontal" share a vertex in the frontal lobe. "Frontal Edge" pieces all share an edge with an "Frontal" piece. Pieces labeled "Cerebellar" share a vertex roughly in the area of the cerebellum. "Cerebellar Edge" pieces all share an edge with a "Cerebellar" piece.

Separate files for each are provided, as well as "Combined" files to print groups out together.

If you choose to scale the files, keep in mind that the holes designed for 3mm x 3mm cylindrical magnets will no longer be the appropriate size. Scaled pieces can still be glued together.
