The Odysseus Hand


Peter Binkley developed this hand for a young boy in Greece.  Departing from the traditional five fingers,the “Ody” hand instead uses three fingers to reduce the force necessary for grasping.  The Ody hand uses the same tensioning system and and leather gauntlet as the Talon Hand and is licensed under the GNU GPL V2.

Assembly Instructions

The most up-to-date files are available for direct download here.  Assembly is very similar to that of the Talon Hand.  From the Thingiverse page, for a hand printed at 100% scale:

  • Wrist hinge: (2) 8-32 x 5/8″ flat head hex screw; (2) 8-32 nylock nut
  • Anchor mount: (3) 3m x .5 x 8mm flat socket cap screw; (3) 3m x .5 cap nut
  • Cable anchor (3) set screws 6-32 x 1/4
  • Cable guide: (4) truss head sheet metal screws #4 x 5/8
  • Palm leather mount: (16-20) truss head sheet metal screws #4 x 3/8
  • Leather to arm bars: (8) 6-32 x 3/8″ flat socket cap screw
  • + a layer of 1″ nylon webbing: (1) 6-32 x 7/16″ flat socket cap screw
  • + 2 layers of 1″ nylon webbing: (1) 6-32 x 1/2″ flat socket cap screw
  • 3 pieces, each ~a foot long 0.05″ round trimmer line (landscaping type) for the cables. Fingertip ends of the line are melted into balls with a lighter so that they catch in the tips.

  1. Hi, we wanted to print a hand for a 9 year old girl who doesn’t have any fingers,
    She has quite a weak wrist movement, and small hand area. this is the first time we are producing a custom sized hand, and we want it to fit her perfectly (since her hand is tiny), please be kind enough to advise on
    1) instructables – step by step (documents or videos)
    2) do we need to cast her hand?
    3) which hand model (thing inverse) file is most suitable for a petit 9 year old girl with weak wrist movement?
    4) we have ultimaker2’s and flashforge dreamers, what are the best settings to print this hand on?
    5) what is the best assembling technique
    6) what is the best fitting technique

    Really appreciate your support in this regard

    Thanks again

    • Hello Heidy – the Ody hand is body powered. There is no code. It straps to your arm and you will bend the wrist to make it close the fingers. 🙂
