In this 2-part lesson, students will design and 3D print their own assistive finger tools to help users with arthritis or a weak grip to do everyday tasks. Using finger tools can eliminate the need to grip objects, which makes them a very simple but effective device for people who struggle with their grip. The lesson begins by teaching students about the various joints in the body and how arthritis affects our joints. They will then be provided with 3D modelling skills in a video tutorial before going on to define, design and 3D print their own unique product.
