This is a bobble-head Skull toy with bobbling brain action.  This toy use a 3D printed spring that supports the brain and makes it bobble.  There is a recess in the bottom that accepts an LED tea light.  the brain and spring should be printed with transparent filament (as shown) for the best effect.

Supports are recommended for the skull base area and you can use minimal infill (10% is fine).

This was made from a couple of different things.  First is the excellent "Human Skull Pot" model by LaLeahTortilla  (https://www.printables.com/model/115570-human-skull-pot-with-drainage-hole/files).

The spring mechanism is based on the excellent bobble head collection designed by 3d-printy (https://www.printables.com/model/224836-emoji-printer-bobbleheads).  Be sure to see his extensive collection of bobble-heads and other items.

Bobble-Head Assembly Tips:
The square spring hole in the skull is a little oversized to aid assembly. Note: For correct orientation, the spring needs to be installed with the flat side of the spring facing forward otherwise it will block the tea light.  Install the spring into the  skull first (crazy glue is recommended).  The tool to install the spring is included here and its use is optional, but handy. Finally install the brain onto the spring.  It also has an oversized hole and so glue is also recommended.  

Enjoy!
