I think students would benefit from actually holding a 3D printed brain than simply looking at images from a textbook. A modeled replica will do justice by allowing the student to rotate the brain and look at the different parts of the brain. They can locate all the lobes of the brain, have a better understanding of synapses and dendrites, and gain an appreciation for everything our brain allows us to do that we take for granted.
Sunnyvale Public Library offers free 3D printing to the public. You must use a 3D modeling software service such as SketchUp Make or Tinkercad to create your object. Afterwards you must set up an appointment with the library staff and bring your saved file created from the software. You can either stay for the amount of time it takes or check in periodically. Only accepts 3D printing models that take 4 hours or less.
