In this 4 part lesson, students will be designing and 3D printing their own unique wrench. Prior to the lesson, the teacher will use the STL provided in the lesson materials to 3D print nuts and bolts at various sizes. During the lesson, students will measure the demonstration models and create an ergonomic wrench to fit the nut and bolt allocated to them! The project focuses on the engineering design process, combined with inquiry-based investigations on ergonomic design.
The lesson can be incorporated into the study of design technology, computing, physics and maths. The material can be adapted for ages 8-16. The curriculum is aligned to ISTE, NGSS, CCSS and UK National Curriculum standards. A comprehensive list of standards met is included in the lesson platform.

Self-Paced Learning Option
PrintLab's student portal is home to the online learning resources required for each of PrintLab’s lesson plans (CAD tutorial videos, explainer videos etc), but it is also structured in such a way that gives users the option to work through each project online in a self-paced manner without a teacher/instructor. The perfect solution for distance learning, 3D printing clubs, passion projects or self-paced learning at libraries and makerspaces.
