This is a contribution to the eNABLE community of open-source prosthetic hands.

The Falcon V2 is a new hand design for test of a number of new concepts. The key features we focused on for the falcon were:
1. High degree of field maintainability: If a finger breaks, it is easily snapped off and a replacement is snapped on. Control cables are fished through one channel and crimped in place, requiring no tools and no knot tying. It is suggested that users are provided with 3-4 extra fingers with control cables run for easy repairs.
