3D print prosthetic foot

myminifactory

This is a revolutionary modular prosthetic foot, fully 3D printable and based on cutting-edge modular architecture principles.The design is completely open source and you can easily download, test, and improve it. WARNING: Be cautious and DO NOT attempt to use this without expert guidance from a skilled prosthetist, despite the impressive gait test performed by an amputee in the accompanying video. This prototype is still under development, and current 3D printing materials will likely fail after only a few uses due to fatigue stress. ABS was used for this example, but you can experiment with PC, nylon, nylon-carbon fiber, or other materials. To assemble this prosthetic foot, you'll need: 3D printed components: Keel, Sole, Top x2 Non-3D printed parts: * 1 or 2 springs for the heel component * 4 M4 bolts (40mm length) and nuts to assemble the pyramid adapter and keel * 2 M5 bolts (20mm length) and nuts to attach the bottom of the springs to the sole * 2 M4 bolts (20mm length) and nuts to connect the top of the springs to the keel * 1 M6 bolt (20mm length) and nut to secure the sole with keel in front * 4 washers to keep the spring securely fastened Watch the gait test video: https://www.youtube.com/watch?v=hhjsND-j9Gs As you can see from the picture, users can adjust the height of the foot by scaling up the Z-axis size of the Top-adapters. The length of the foot (1cm = 1 foot size) can be adjusted by moving the sole, and the stiffness or amount of springs can be modified according to individual preference.
