Overview

In this 2 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 a wrench to fit the nut and bolt allocated to them! Enrolling in PrintLab Classroom will give you complete access to the teacher training material and lesson documents. This includes content to help you prepare and deliver the lessons along with design tutorials so you become familiar with the process prior to teaching it in the classroom.
