With the help of the NASA Ames SpaceShop Rapid Prototyping Facility, the Kepler team has created a 3D-printable puzzle of the spacecraft for educational purposes.
The model files and documentation are available on our GitHub repository at https://github.com/KeplerGO/kepler-3d-printing-model. We would love to hear about your experiences if you decide to use this resource for educational or outreach purposes,
