SEE BELOW FOR OUR CURRENT DESIGNS AND LINKS TO THEIR FILES:

 

NEWRELOADED

Raptor Reloaded – Widely used, easy to assemble with written and video tutorials available.

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

The team behind the original Raptor has released the Raptor Reloaded, an updated and re-factored version of the Raptor Hand created by Andreas Bastian, Frankie Flood, Peter Binkley, Jeremy Simon and Ivan Owen. The entire device was modeled in Fusion 360, a free CAD tool that can import and export most standard solid body modeling formats such as STEP and IGES. By designing the hand in a tool compatible with numerous CAD packages, we hope to lower the barrier to contribution to the e-NABLE project for engineers and designers. The Raptor Reloaded is shared under the BSD License.

 

PHOENIX
PHOENIX HAND – Widely used, improvement of the Raptor Reloaded design and has assembly instructions available.

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

This design was created by Jason Bryant, e-NABLE volunteer, researcher and teacher at Shandong University in China. His design is an amalgamation of the Raptor Reloaded hand and the Falcon V1 hand designed by Dr Adam Arabian from Seattle Pacific University. The Falcon V1 was the first e-NABLE 3D printed hand prototype to use orthodontic rubber bands as opposed to the elastic cords that current devices use.

TEAM UNLIMBITED ARM – Isabella Edition – Most popular and easy to assemble arm design with instructional videos and written instructions on thermoforming and assembly.

ELBOW DRIVEN: Users must have a functional elbow that bends to force the fingers closed on the hand.

This device was created for those that have a functional elbow and a considerable amount of forearm but no wrist or not enough wrist/palm to power a wrist driven device. This design is for those who have too much forearm for the RIT arm but not enough wrist/palm for a wrist powered device.

This design comes from volunteers Stephen Davies and Drew Murray of Team Unlimbited with inspiration from Christian Silva and Po Paraguay.

NEWospreypage
The Osprey Hand – Becoming more widely used and has video instructions available.

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

The Osprey is the latest wrist actuated assistive device to come out of the Alderhand series created by Peter Binkley and Peregrine Hawthorn. (Others in the series are the Talon and Ody hands.)

The Osprey is the first ever hand designed specifically to use a Bowden push-pull mechanism. Rather than use thin braided line, the Osprey uses thick nylon monofilament cables.

NEWCYBORGBEAST

 Cyborg Beast –

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

Developed by Jorge Zuniga and his research group at Creighton University, the Cyborg Beast is one of e-NABLE’s most popular designs.  Among its features are textured finger tips for improved grip, Chicago screw joints, protected cable routing through the body of the palm, and integrated tensioning system in the gauntlet.  The Cyborg Beast is licensed under the Creative Commons-Attribution-Non-Commercial license.

NEWPAGERAPTOR

Raptor Hand

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

Developed collaboratively by some of e-NABLE’s top designers, Peter Binkley, Andreas Bastian, Frankie Flood, Ivan Owen and Jeremy Simon. The Raptor Hand is designed with ease of printing and assembly in mind. Features include 3D printed snap pins, a modular tensioning system, and compatibility with both velcro and leather palm enclosures. The Raptor Hand is licensed under the Creative Commons-Attribution-Share Alike license.

NEWTALONPAGE

Talon Hand 2.X

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

The Talon Hand is probably the most durable e-Nable hand design and boasts the greatest grip strength, but relies on a user with a greater range of motion. This design was created by Peter Binkley and his son Peregrine Hawthorn who is also a device user. It is also one of the more challenging and time-consuming e-Nable device to assemble. The Talon mounts onto a leather shoe-and-cuff to make it wearable by the user. The Talon Hand is licensed under GNU GPL V3.

 

K1
The K-1 Hand 

WRIST DRIVEN: Users must have a functional wrist and enough palm to push against the device to force the fingers closed when the wrist is bent.

 

The K-1 hand is an evolving design and is an elegant, anthropomorphic hand that utilizes commonly available materials and 3D Printing. There is no metal hardware and all cords are recessed for aesthetic purposes and for a better quality user experience. This hand is intended for adults and young adults – including female veterans, teens going to prom, or an individual going to a job interview.

The anthropomorphic design and recessed cords allow the user the option of wearing a glove over the device.

 

NEWODY

 Odysseus Hand

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

The Ody Hand is intended for younger users, is quite durable, and works very well printed at smaller scales. The three-digit design, created by Peter Binkley, offers lower grip resistance than five-fingered devices, so it requires less strength to operate. Its shoe-and-cuff construction process is very similar to that of the Talon Hand. The Ody Hand is licensed under GNU GPL V3.

 

NEWflexyhand

Flexy Hand and Flexy Hand 2

WRIST DRIVEN: User must have a functional wrist and enough palm to push against the device to force the fingers closed when wrist is bent.

The Flexy Hand 2, designed by Steve Wood, is a wearable prosthetic device made using flexible hinges. Using flexible filament for the hinges means that no elastic cords are necessary to return the fingers to their outstretched position. The Flexy Hand 2 is shared under the Attribution – Non-Commercial – Share Alike license.

knickfinger
The Knick Finger

Created by Nick Brookins, this partial replacement finger design is a parametric finger that can be customized to a user’s individual measurements. This has been released to the public domain via the Creative Commons Public Domain Dedication license.

 

NEWowenfinger

 Owen Partial Finger Replacement

Developed by Ivan Owen,the co-creator of the original Robohand, this partial replacement finger is a parametric finger that can be customized to a user’s individual measurements using the Thingiverse Customizer web-app.  This has been released to the public domain via the Creative Commons Public Domain Dedication license.


NEWPAGELIMBITLESS

Limbitless Arm

BELOW ELBOW DEVICE: User must have a portion of the arm from below the elbow for this device to fit properly.
MYOELECTRIC: This device is used along with sensors and motors that use the muscles electrical signals to make the fingers move.

Developed by the UCF Armory (University of Central Florida), led by Albert Manero, the Limbitless Arm is e-NABLE’s first myoelectric design. The Limbitless Arm is licensed under the Creative Commons-Attribution-Non-Commercial license.

Please visit this page for details on where to download and how to assemble.

 

NEWRITARM

RIT Arm

ELBOW DRIVEN: Users must have a functional elbow that bends to force the fingers closed on the hand.

The RIT Arm is an adaptive device people an arm with an elbow but no wrist. It can be actuated by bending the residual elbow or via a bowden cable connected to a shoulder harness. The arm was originally developed by e-NABLE members at Rochester Institute of Technology.

Please visit this page for details on where to download and how to assemble.

 

 

bowholder
SHEA’S BOW HOLDER

This is a viola bow holder that was created for a young girl named Shea by Frankie Flood.

At the moment this bow holder has a fixed wrist, but he is currently developing a moveable wrist holder that will be published here as well.

Trumpetholder

KARUNA’S TRUMPET HOLDER

An adaptive device for use with a trumpet, created by Caitlyn Driver for a young man named Karuna who was born missing fingers. Caitlyn created the device at the University of Wisconsin Milwaukee under the mentorship of Frankie Flood.

  1. Brilliant, I only wish you were in the UK as well, as I would jump at the chance at having one of these, having no fingers on my left hand, just small little stumps and only a thumb that moves. Great idea and so good that you are helping so many. Bravo.

  2. I find this very very amazing. by any chance, this cold reach panama? i know a 6 year old boy who was born healthy but a strange infection on the blood cause the Dr to cut both hands and both legs. he is only six a child full of energy and a smile that would melt who ever i have seen what you guys so. and was wondering if this could be something this child could use?

  3. Fantastic! I am oncological orthopedic surgeon from Brazil. I think that your inniciative can help thousands around the World! Congrats!

  4. @ Warm Fuzzy Revolutionist. Can’t see how to reply to your response at 3:37am. but I gotcha.
    I now understand the system; e-nable organise the matching. I was too eager to jump in where I should have waited.
    I have now added myself to the map and filled in the form.

    I have one major printing problem; “warping” to solve before I can accept requests. I think I’m going to have to build a heated bed next. However, I have successfully printed some objects in PLA and PETA. Does it need to be ABS?

    • Andy Gaffney, this is a quote;- “Materials

      Materials are still an area of active exploration. e-NABLE members are currently fabricating hands using ABS, PLA, and Nylon, each of which has specific printing requirements.

      Branebot put together a great Instructable describing the process of printing a Cyborg Beast in Nylon and dying it.”.

      So, while ABS and Nylon are preferred in terms of having a bit more “give” than PLA, no, you can use PLA for prints. That’s how I read the webpage…

    • Hi Andy I have had the same problem with the prints warping I found if I fastened a 3mm sheet of acrylic to my bed, my prints would stick to these and not warp but would pull off after finished

  5. Hi there, I have a friend who lost both arms as a child in a terrific accident. He is a bright young 26 years old man. He lives in Russia and doesn’t have any prosthetics, he simply can’t afford them and Russian ones are very heavy and painful to use. Is any chance you could help or direct me to the organizations who could help this young man? He has a channel on YouTube – Сергей Лайков. Thanks a lot. Natalia Holmes

  6. I have a 6year old son who was born with stump at his left wrist. No thumb or fingers. I still find it very hard to this day. He is awesome and deals with it with great strength. Would he be able to try this printed hand in the UK??

    • Hello!

      YES! We have volunteers in the UK Now!
      Please email us at letsgetstarted@enablingthefuture.org and we can get you started on getting matched with a volunteer near you!

      Thank you!!

  7. I AM PRINTING MY FIRST TRIAL HAND. I SELECTED THE ODYSSEUS HAND..I AM PRINTING IT TO SCALE AS SHOWN ON STP FILES….DOES ANYONE HAVE A PATTERN FOR THE LEATHER/PALM PART OF THIS HAND?
    I CAN’T SEEM TO FIND IT ANYWHERE.

    • Hi Sal! YES!

      Peter Binkley does! His contact info should be on the thingiverse page where you downloaded the ODY hand files!

  8. Can practice hands be donated? I have a smallest raptor hand built as a test with no user.

  9. I am wanting to print a hand for a young girl in our community as part of my capstone project. Is there anything me or my college needs to do before we proceed?

  10. Hi! My name is Ana Paola and I’m from Mexico, im very interested to work with you. I’m a mechatronic student and it could be really nice to know more about you! Nice work, im very impressed. Thank you for doing this work for helping people (:

  11. Its truly heart warming.I had been searching for such help after reading a story about a little Indian girl whose arm was cut by a violent mob during riots.It was published by a women’ organisation who helped her reach hospital. I have written to them about you hoping that help find it way to the needy victims.Thank you and keep it up.

  12. Hey i am abheerup, robotics engineer, grad. student.

    I saw your videos…they are great..i had the same vision. & so i recently completed a project on “muti-phalange controllable robotic prosthetic arm” using myoelectrics.

    & it can open n close individual fingers as per the amputee’s choice. That’s an advancement over your arms..
    I’d like to work with you guys.

    • Hello Abheerup! Please feel free to reach out directly to the limbitless team through their email information above!

  13. its so awesome that people do this! using new technologies to make the world a better place!!!!

  14. Hi there, nice work!
    I have a palsy of the posterior interosseus nerve
    I would need a device that allows me to open the fingers when I raise my hand carpus
    Some advice for me?
    Thank you
    P.S: someone from Italy?

  15. Are there existing blueprint style renderings of these with measurements …. a 3d printer is beyond reach bit I have access to good tools and light weight hardwood lumber

    • Hello Harold – I do not believe so. They are created digitally.
      If you are in need of a device – our volunteers can help print for you and you could assemble if you wanted to.

  16. My daughter was born with a partial left hand conventional prosthetics do not work for her. How do I go about getting one of these wonderful devices for her.

  17. Hello guys I’m from India. I’m really happy to see what you are doing
    A friend of mine like to have printed hand with which she can play guitar . Whether any of the available designs be used for that. Or can you guys help me make one

    • Hello Varun! We currently have a design contest going right now – hoping to get some entries for that sort of thing but until then – you can click on the “Get involved” tab on the website and visit the Google+ or Forums and volunteers may be able to assist you with that!

    • Hello Carlos! Please fill out the intake form and welcome!

  18. Hello, I am a student at Raisbeck Aviation High School which is a STEM and aviation focused school in Seattle, Washington. I love what you guys do and I have many fellow students who are very interested as well. We have access to multiple 3D printers and I think it would be great to start a club and fund raise to be able to truly get involved and make hands. Our school is very open to projects along these lines but I need to figure out some logistics before I go to the principal. Do you think this could work? Any thoughts or suggestions?

    • Hello Veronica! My name is Jen Owen and I am the wife of Ivan Owen – the fellow that created the first hand. We are actually located near Seattle as well and I would be happy to help!

      Please email me at jen.owen@enablingthefuture.org 🙂

  19. This is awesome. I have 3 3d printers I use to print and sell items for a local charity. Would love to put them to use building hands.

  20. My hubby and I have a 3D printer and a granddaughter who needs a mechanical arm and we are in Australia and we would like some tips and tricks and to how to customerise and fit the arm. She has an elbow but no wrist or hand so we are looking at the Derek style arm

  21. Hello, we are a small company in the Netherlands. We have a 3D-printer and would love to help. What are the possibilities? Are you also located in the Netherlands?

    • Hello! Our e-NABLE Community is global! We have volunteers all over the world and are always excited to find more! Please visit our Google+ community and say hello and ask if there are other volunteers in your area to connect to! Ultimaker is our website sponsor and they are in the Netherlands too! I know we have some volunteers there!

  22. Hi e-nable, there is a saying in Nigeria here. May God Blessing you emmersly. I work with a prosthetic and orthotic firm here in Nigeria that markets and fits prosthesis for individuals who can afford it(ottobock). Here in lies the problem, for every 5 people who can afford what we offer, 25 others can’t. Such is the case all around the country.

    I have been looking for something that fitts the range of the many who can’t and possibly develop a charity out of it for some worst hit war tore areas in the northern part of my country.

    What i have seen so far on e-nable shows that its truly possible.

    Currently there are no 3D printers in my country, but is it possible to pick a design for a patient and have his/her spec sent to someone in another country to have it printed and sent back to us here.

    Looking forward to hearing from you soon.

    Brian Chijioke Ahamefula

  23. I haven’t visited the e-Nable web site for several months so I was wonderfully surprised to see the changes. Having clear pictures and descriptions of each available hand and watching the videos of the young girl assembling the Raptor was fantastic. I have purchased a 3D printer and will be experimenting with it and different plastics to see what I can make. Maybe an e-Nable device in the future.
