This Mechanical Prosthetic Concept was designed in zBrush by Jose Alves da Silva for use as a development platform for Field Ready, a global non profit organization specializing in disaster relief efforts.
The primary goal is to have a fully 3D printed prosthetic hand that does not require any screws, nuts/bolts or tools to assemble (as those items may be impossible to source in remote areas). We used fabric strips and elastic bands cut from shorts for the test print. The secondary goal was to make the files accessible for development/design changes by others - so it could be improved and modified for specific needs.
We invite you to download this model, test, and modify it.
