Updates to this design as of 11/6/14:

  • Increased the size of the cable & bungee channels
  • Improved the shape of the fingertip
  • Increased the thickness and durability of the structure to prevent the fingers from bending backwards
  • Added bars to tie the cable & bungee off too
    This is the first 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.
  • All measurements must be in millimeters.
    This thing contains the socket that fits over the finger stump and the artificial finger tip.
    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. :)
    This design is part of the ongoing work of the E-Nable group.

Hi Ivan,

I want to make your partial finger replacement design but I have a question:

Can you make a video of the partial finger replacement ASSEMBLY?

Please, because with the images is very difficult and with the video tutorial of assembly it would be very easy and if you can explain how can obtaining measurements it would be very good.

My 8th grade students are making one of these for a local college student who is missing 2 partial fingers.
We need the .stl files for the socket and tip. They used to be here, I thought...where did they go? Thanks.

Greetings Debromning46 - this is a customizable thing, so in order to obtain .stl files, first open it in the Customizer using the button to the right of the photo. You can then enter in measurements to modify the design and the .stl files will be automatically generated. The .pdf file in the section labeld "Thing Files" (accessed with a button located under the photo) has information in it to guide you through the process. Feel free to email me at [email protected] if you have additional questions or if I can help further :) Thanks!
