Second Degree Hand

thingiverse

This mechanical hand boasts a functional thumb and two degrees of freedom in motion, allowing side-to-side movement alongside raising or lowering the fingers. Unique features include springs on the tuners for improved grip and OpenSCAD files for customizable STL creation. Although no mechanical thumb option is currently available in this design, interested users can request its addition. The designer is working on an updated version but considers the current one mostly complete. As with all 3D-printed prosthetics, use at your own risk and consult a professional for assistance.

Version 3 updates include reduced parts for improved strength, smoother motion with optional bearings, and a switch from printed pins to 3mm PLA. Customize OpenSCAD files by saving all .scad files in the same directory and adjusting advanced preferences and parameters in included files. Print the necessary hand, finger, and gauntlet parts for assembly.
