Modular wheelchair extra arm

thingiverse

Fully 3D Printed Modular wheelchair Arm I developed a novel idea for this modular wheelchair arm that I came up with: It can spin and pivot, allowing users to attach different holders at the end based on their needs. Innovative Approach As part of my research into daily challenges faced by people who use wheelchairs, one issue that stood out was how hard it is to see themselves in a bathroom mirror. Since most mirrors are mounted too high, users can't use them effectively even with a smartphone's front-facing camera as an aid. Users need both hands free for personal grooming and hair-fixing. With this issue in mind, I realized that having an adjustable arm connected to the side of the wheelchair would greatly simplify things, providing additional usability not just in bathroom contexts but also other areas. Key Constraints I set two main requirements for my design: The entire thing needed to be made from 3D printed components using no external hardware or tools, and everything should be easy to adjust based on a user's unique needs. All parts use the same standard threaded/bolt system. This standardization allows users to extend their arm as much as necessary by adding new shafts or connectors wherever they want them. The design software I used for this project is OpenSCAD; its code, included in the files (keep in mind that it's not my most elegant work!), demonstrates how each component was designed from scratch.
