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.

The car had been assembled perfect it is working fine. At the end I use a rubber band around the rear weels to improve the traction of them.
Include some space in the rear wells to put a traction rubber.
