Jemari

The open-source Jemari 3D printed hand is revolutionizing prosthetic technology by making it more accessible to amputees. Current high-end robotic prosthetics can cost up to $100,000, but emerging technologies like 3D printing are cutting costs down to under $500. All the necessary information to create your own Jemari hand is available right here or on my website. Moreover, anyone can contribute their ideas and improvements to enhance and customize the designs. When ready, step-by-step instructions on how to make a Jemari hand will be available at www.paksudelta.com. For feedback and suggestions, please leave them in the comments section. Thanks to Thingiverse for allowing us to share this technology.
