Lesson Overview

In this project, students will design assistive clips that attach to objects to make them more accessible for people with arthritis or a weak grip. The lesson begins with small-scale experiments called tolerance and flexibility checkers, where students design and 3D print various sized clips to determine the optimal shape for a pen clip. Students then go on to develop their clips into assistive writing aids in the form of a pen grip. With their new skills in place, they are challenged to design a unique assistive clip to fit an object of their choice. The final part of the lesson involves 3D printing, testing, analysing and suggesting improvements to their end-product.

Subject Areas

The lesson can be incorporated into the study of maths, biology, design technology and computing. 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.

In this project students will:

  • develop an understanding of tolerance and flexibility for 3D printed parts

  • conduct an experiment to explore the tolerance and flexibility of 3D printed clips with varying shapes and dimensions

  • use design-thinking and sketching skills to develop a concept for an assistive clip

        • use 3D modelling software to design their own assistive clip

        • use 3D printers to manufacture an assistive clip

        • analyse their work and the work of their peers to suggest improvements to their designs
