Build a printable version of the Trautman Hook, an out-of production prosthetic device.
This is derived from work by the the Open Prosthetic Project. Here is the description from their webpage:
The Open Prosthetics Project is producing useful innovations in the field of prosthetics and freely sharing the designs. This project is an open source collaboration between users, designers and funders with the goal of making our creations available for anyone to use and build upon. Our hope is to use this and our complementary sites to create a core group of “lead users,” and to speed up and amplify the impact of their innovations in the industry.
This instructable will start with some information on their design, then we will make modifications to create a version that can be built using low cost 3D printing technology.
Hopefully, we will end up with a robust working model that can be easily reproduced. I probably won't get there with just this instructable, but I hope that this will be useful to others with the same goal.
I should note that I don't represent any of these groups. I also make alot of mistakes.
This is entirely built on the work of the open source community, including:

Step 1: Collect resources
Open Prosthetics as already done design and prototyping work. I am just building off their work in a way that seems compatable with the MakerBot 3D printing equipment.
Bre Prettis at Makerbot pointed me towards this project, he posted STL files here: http://www.thingiverse.com/thing:2114
Availble resources include:
Previus work (drawings, photos) - http://openprosthetics.org/concepts/55/the-trautman-hook
(they have also posted their design files, but I can't seem to open them)
