This design is part of the ongoing work of the E-Nable group. For more information on where to connect with people who can help someone in need with sizing, printing and/or assembly a mechanical hand please join the e-NABLE Google+ Community entitled, e-NABLE: https://plus.google.com/communities/102497715636887179986 For more information and stories: http://enablingthefuture.org https://www.facebook.com/enableorganization This is the second in a series of 3 things that, when combined, can be used as a device for some partial finger amputees missing more than half of their finger. It's customizable so that it can be adjusted to the size of the user's hand and fingers. Included in the "files" section is a PDF document with a measurement guide and instructions on assembly. This thing contains the cable guide worn on the back of the hand. A video showing someone trying out the device can be seen here: http://youtu.be/WlfS02OAKcU I see this as just a starting-point (and a rather rough one at that). I would love for other designers to take the source files, experiment, re-mix and improve upon this. :) Included in the "files" section is a PDF document with a measurement guide and instructions on assembly.
