This design is created to assist individuals with limited hand mobility to drive safely and comfortably. It adheres to three fundamental criteria: user-friendly, easy to manufacture, and budget-friendly. The primary function of the device is to grasp the steering wheel securely and enable effortless turning. The model is primarily printed using PCTPE for optimal comfort and performance, while any rigid components are made from PLA due to its ease of printing. To produce the strap, start by printing the front piece. Next, print the second piece without support, pausing just before the printer bridges the circular opening. At this point, carefully insert the front piece's circular boss into the opening using super glue, taking care not to apply excessive glue that may clog the print head or interfere with printing. This step is optional for users with larger printers, but I designed it to fit on even the smallest devices. By combining melted plastic parts from a 3D pen and hot glue for hard-to-reach joints or contacts between dissimilar materials, the assembly process becomes more manageable. The end effector is entirely composed of PLA and assembled by inserting the moving arm into the slot of the fixed arm and pressing the pin through. The components should fit snugly without requiring further processing. If a tight fit results in an immovable arm, either sand down the moving arm or use an X-Acto knife to remove any obstructions present in the fixed arm.
