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.

All files for this design can be found on Thingiverse, HERE. For detailed instructions on which files to download and print, see below.

Cyborg Beast Assembly Materials Kit Now Available

You can purchase an assembly materials kit for a Raptor hand from 3D Universe by clicking here. This kit includes all of the materials needed to assemble a Raptor hand or a Raptor Reloaded Hand.

A discount is available on these kits for e-NABLE members who are actively involved in the charitable fabrication of these devices. Email for more details.

A portion of every kit sold will go towards supporting and the e-NABLE community!





An Important Note About Assembly

The most common mistake when assembling e-NABLE Hand devices is improper tensioning of the non-flexible cords. When the non-flexible cords are tied correctly, the base of the palm should be inclined about 30-45 degrees compared to the base of the bracer (the part that goes over the arm). This will allow the recipient to activate the device without having to bend their wrist so far downwards as to cause discomfort.

As an example, the below image shows a properly tensioned Phoenix v2 hand. While this is a different design, the Cyborg Beast hand should be assembled at a similar angle as what is shown here.

      I’m also located in Mexico City and just joined the community. I have a 3D printer and would love to both print and design.

      If you have someone that is in need of a device who is missing fingers – please send an email to our matcher team at and they can help find someone near you to help! It may take a few days for them to get back to you as we are all volunteers and do this in our free time so please give them some time to get the info to you!

    My name is Spiro. Im a 25 year old man from Greece now living in the UK.
    First of all i would like to congratulate you on such a wonderful achievement! I myself was born with missing digits on my left hand due to congenital amniotic band syndrome. Its where the amniotic sac constricts a part of the body and prevents it from developing when in the womb. I have coped without any prosthesis or support whatsoever my whole life because of the cost of having something like this done. It is absurd and ridiculous to price a prosthetic at such a high cost as 35k and over! But thanks to people like you there is hope for someone like me. What would it take to possibly get a hold of one of your devices?

    Best wishes,
    Spiros Pouliasis

    Hello I’m Jeff and I live in the Philippines. Would you know anyone in this area who can help me have this hand… I lost my right hand due to an accident but I still e my carpal and wrist intact… My dad lives in LA in the united states maybe I can have one shipped to him then he can send it to me here in the Philippines… I really appreciate all these things your doing for people like me.. All the best.

    My husband lost his arm to the shoulder. Are these a possibility for him? He has had the same prosthesis for 37 years because of cost.

  5. Johan Threels Reply

    I have a daughter who has one finger. She has seen on the internet hand and would love to have one. Only handmade for someone who has no fingers. Is there a possibility that someone can customize the file for her. There is a 3D scan of her hand made so it might change what is easy.
    Yours sincerely

    Acabo de leer un articulo en la revista city energy en Chile, se me llena el corazón con la forma como desarrollo su proyecto, sus objetivos, los logros y el tiempo invertido. Me queda claro que con perseverancia y su objetivo, a logrado su fuerza. No tengo impresora, ni grandes recursos, solo cuento con mis manos y mi creatividad. Nose como pero quiero ayudar, soy Diseñadora industrial, mi correo personal

    Hi there-my new born is due in April and I’ve learned he will not have a left hand. There is no limb difference otherwise, he has everything up to his wrist but I’ve been advised that the sooner you introduce children to prosthetics the better. Is there a size available for children 6 month olds? Additionally we don’t have a 3D printer. Is there a way we can order one? Thank you so much and this is amazing!!!

    • Jen Owen - E-NABLE Reply

      Hello! Congratulations on your baby!

      We do not recommend putting these on children under the age of 3 as they have some very small parts that can be choking hazards for younger children who put everything in their mouths!

      You will want to work with a hand specialist or prosthetist who specializes in babies and toddlers and then when he is old enough to try a 3D printed hand – we can certainly help you!

    Hi there, I’ve trying to make a hand for some time now, but ran into a few problems. There seems to be multiple variations of the gauntlets; where can I get access to the gauntlet with the slits for the velcro as well as the twisting type tensioner mounting?

    Hello, I am in your database download images seem to be is incomplete, I am very urgently need to know the method of making 3 d prosthetics, I come from China, this technology is not here, I’d like to cooperate with you, and popularized in China, looking forward to cooperating with you!

    Hi everybody,
    Sorry for posting this here but I didn’t found any user forum or so. I am having issues printing the gauntlet for the cyborg beast hand :
    In fact, the contact with the printer plate is too small and is not flat, and the printing always ends up as a big mess. Also, at some point, the printer tries to print in a point of space corresponding to the gauntlet tips, and it’s the least to say that it doesn’t really work. I’ve tried to rotate the 3d model so the gauntlet tips touch the printer’s plate, but yet the surface contact is still too small, and the printer starts printing wires that detach from the model.
    Do anybody ahad issues with it too ? Or are you all succeeding in printing it without any problem.
    I am thinking of printing this modified gautlet instead :
    Or maybe flattening the original model by myslef.
    Thanks for your help,

    Hello ,
    I printed the cyborg beast and the gauntlet does not have a place for the tendons to be inserted, also the Instruction Manual is not opening. Is there a way I could get the Instruction manual for the Cyborg Beast to be sent to my email or access it in any other way because I tried multiple times to open it but failed. It says this “This XML file does not appear to have any style information associated with it. The document tree is shown below.

    The specified bucket does not exist

    The project is very good and to become more comfortable and not hurt the boy’s hand and I think a glove with specific material and whistled his hand would be an idea to be considered.

      We now use medical grade foam where it is available but some people are also creating other types of padding!

  16. Adrine Reply

    What about a soft silicon like substance to help in pain and adjustment? Or maybe make it longer in the arm to increase the strong and stability of arm?

    • Jen Owen - e-NABLE Volunteer Reply

      There have been many improvements since this first design! Please visit the Google+ community or our forums! A lot of volunteers in there to help!

    Hi there,
    First of all thank you so much for doing such a noble work. I am a senior Electrical and Computer Engineering students and fr my senior design project I am working on a EMG Controlled Forearm Prosthesis. I would like to use this design for the actual hand, and my question is if is possible to fit servo motors inside the hand to actuate the tendon lines? I would also love to shared my project with this community so more people can be benefited by this technology. Email me at

    • Jen Owen - e-NABLE Volunteer Reply

      Thank you so much!

      Best place to find out about that would be in the forums but you are always welcome to take the design and “make it work” and we just ask that if you use it for part of your final device, that you give credit back to the designers and community!

      Thank you!!
