Basic Open Source Limb Prosthetic created for Michigan Tech's EE4777 3D Printing class.
To print, you will have to comment out certain parts. You will want to print out the "claw" portion separate from the bottom "arm hold" portion, and then slide the claw into necessary cutouts when completed.
Also, important note - you should go through the code and make sure the measurements are correct for limb (such as height and radius).
Note: I made a stupid error in conversion, so the object is very small. Best option would be to go through code and size it personally, and I will (hopefully eventually) update it to be more accurate.
