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.
