Robotic Hand v3.0 by armjunkie

Thingiverse citizen armjunkie has shared version 3.0 of his seriously amazing robotic hand.  As with the prior version, the entire model is detailed and intricate.  Each joint in each finger is tensioned using dental rubber bands and controlled with fishing line.  In true Thingiverse spirit, armjunkie responded to a comment providing even more detail about how the behavior of the hand’s opening and closing motions can be customized by the number and placement of those same dental rubber bands.

One of the things I particularly about this model is the split photo above showing his designs¹ alongside the reality.  There is just something extremely satisfying about getting to see a design completely come to life exactly as you have planned. ²   Such intricate designs portend great things for the possibilities of creating plastic automata, puppets, and prostheses.

Robotic Hand v3.0 by armjunkie

My first Robotic Hand (version 2.0) was designed with no 3d printer in mind. Version 2.0 had many shortfalls and difficulties. Since then, I've gotten a TOM and have learned how to design with its limitations and benefits in mind. I present to the 'verse Robotic Hand Version 3.0. Ver 3 requires less non-printable hardware, it requires less plastic to print, less printing time, less post-print work (very little sanding), and far less pull force is required to manipulate.
