Thank you for visiting our website! e-NABLE volunteers are working hard to create free 3D printed hands for children all over the world who have been born missing fingers or who have lost them due to accident, illness or war. To date – we have created nearly 1000 free “Body powered” 3D printed devices for over 700 individuals and the numbers grow daily!
All of our current designs are shared open source so that anyone that would like to make one for themselves, their child or someone they know – can take the files and create a device or improve upon the design and re-share it back to the community! (Please feel free to join our growing Google+ community and share your ideas with us!)
If you have a 3D printer and would like to help create hands and arms for people in need or if you are in need of device yourself, please visit our “Get Involved” page and fill out our intake form!
If you do not have a 3D printer but would still like to help us “give a helping hand” – please consider making a small donation to help us on our quest to supply free hands to all who ask.
We are actively working on new designs for children (and adults) with all different types of upper limb differences but most of our designs require a functional wrist or elbow to power the mechanical devices. We have some experimental designs that are being tested and created by various groups within the community.
One of these designs is the “Limbitless” myo-electric arm that you may have seen in the “Iron Man” video recently!
This experimental design was created for individuals with above elbow limb differences by a team of students at University of Central Florida. Only a few have been created so far and they do have a wait list. This is currently the only team that is able to create these devices as they require more time, electrical expertise and a more robust printer than the average e-NABLE volunteer has to print with.
Developed by the UCF Armory (University of Central Florida), led by Albert Manero, the Limbitless Arm is e-NABLE’s first myoelectric design. The Limbitless Arm is licensed under the Creative Commons-Attribution-Non-Commercial license.
All files for this design can be found on Thingiverse, HERE. For detailed instructions on which files to download and print, see below.
For more information on this design, please contact the Limbitless team directly: [email protected]
The instruction manual can be downloaded HERE. It has been estimated that it costs approximately $350 for all of the required materials to produce a Limbitless Arm.
