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.
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.

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.
