3d model description

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.

Post-Printing
The model shown is printed with grey filament. A lighter shade of grey with a bit of pink in it would be ideal and might be possible with a bit of paint.

The holes for the 3mm x 3mm cylindrical magnets often print with small burrs inside, so it is a good idea to clean them out with a 1/8 inch drill bit before inserting the magnets.

It is important to pay attention to magnet polarity or the pieces won't snap together! The pair of magnets on each edge are inserted with opposite polarity. Maintain the same pattern around each edge and across each piece. Use dab of CA glue to hold the magnets in place.

How I Designed This
The digital "Human Brain" file by benkrasnow was sliced in Blender using this icosahedron slicer: https://www.thingiverse.com/thing:4146748
