A complete design, print and build challenge
Turn a 3D printer into a hands-on engineering challenge. Students design and print a lightweight pencil holder, fit it to the tracing car, then test it on a course without dropping the pencil.
See how the supplied electronics and a student-designed pencil holder come together in a working tracing-car challenge.
Why it works in the classroom
The project gives students a clear brief and a physical result they can test. The supplied base model provides a practical starting point while leaving room for original ideas, measurement, iteration and discussion.
Learning opportunities
- 3D design, measurement and iterative prototyping
- Electric motors and simple electronic circuits
- Velocity, distance, time, gravity and centre of gravity
- Testing designs against a practical performance brief
