This toy car is easy to 3D-print and quick to build. It is the first project demonstrating the new and fully 3D-printable educational construction set toy; you can download from https://stemfie.org.
This project exhibits the retention and controlled release of energy to achieve motion. The inspiration for this design is borrowed from science classes in schools, using the mousetrap challenge.
