3D print prosthetic foot

myminifactory

This is a modular prosthetic foot, a fully 3D printable prosthetic foot, using modular architecture principles.The design is open source and you can download, test it and improve it. DISCLAIMER: Be careful and DO NOT use it without help of a prosthetit, although in the video the amputee performed a gait test using the prosthetic foot, it is still a prototype and current 3D printing materials will probably fail after a couple of uses (because of the fatigue stress), I used ABS but you could test it with PC, nylon, nylon-carbon fiber or other. To assembly the prosthetic foot, you need: 3D printed parts:KeelSoleTop x2 Non-3D printed components:1 or 2 spring for the heel component4 x M4 bolts (40mm length) and nuts for assembly the pyramid adapter and the keel2 x M5 bolts (20mm length) and nuts for assembly the bottom of the springs to the sole2 x M4 bolts (20mm length) and nuts for assembly top of the springs to the keel1 x M6 bolt (20mm length) and nut for assembly the sole with keel in the front4 x washers for keeping secure the spring Gait test video:https://www.youtube.com/watch?v=hhjsND-j9Gs As you can see in the picture, one can adjust the height of the foot by scaling up in Z the size of the Top-adapters. Adjust the length of the foot (1cm = 1 foot size) by adjusting the position of the sole; and one can modify the stiffness of the springs or its amount according to the user preference.
