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 (video) or via a bowden cable connected to a shoulder harness (video). The arm was originally developed by e-NABLE members at Rochester Institute of Technology (video).
STL files and instructions can be found HERE.

I am not seeing the files for the fingers.
Made one of these for a 3rd grader in Austin Texas. Completed the hand/arm on 12/11/14. After a few practices, she picked and apple and handed it to me (her teacher).
I do have some technical questions for the creator(s) of the RIT.

Is there anyway to combine the RIT (elbow powered arm) with the raptor hand? My son has a malformed hand but he can’t flex his wrist.
Hi Stewart!
We are actually just about to release the “Raptor Wing” design – just for cases like this! It takes the raptor and the RIT arm and merges them together for kids who have no wrist or cant flex it.
Are you in the Google+ group? We will be releasing the files there first and getting some testers first before putting them up to the public.
This is great news! He could not flex the regular raptor hand enough to make it functional. And yes, I’ll be following the raptor wings developmental progress on the Google + group. This could be the solution we’ve been looking for. Thanks!
How can I source this for my daughter ?? I have no access to 3D printers etc and am not very techinically minded. Id love some more info and so would she 🙂
Hello Andy! Please visit our “Get Started” page and fill out the intake form!
Hi Jen! We are helping a boy who has the elbow joint and forearm but has no hand (amputation at the hand joint). I guess the same case of Stewart. Could you please let me know if the Raptor Wing design is the best choice? Is there already any files to try it or should we adapt the RIT Arm? Thanks!
Hi Charles! I think the Raptor wing would be a great place to start!
Hi! We are building this arm using a DimentionSST1200es, and the support material is stuck in the holes for the non-elastic string. We’ve tried cooking the material out many times to no avail. Does anyone have any advice for this or had this same problem?
Thank you!
Hello! Best place to get that answer would be in our forums and Google+ community!

Hi!
Congratulations for the sponsors and members of this huge initiative.
I got interested in printing this for my girfriend, but I believe the fingers file is missing, isn’t it?
May I use from another project?
Thanks a lot
thank you Lucas! The files for the fingers are missing from the RIT design?
Yes, Jen Owen! Thanks for your attention.
Not only for me and also for “IronShutterFly Photography by Ralph Ferro”, as he said in the very first comment above.
I am very excited to give her as a X-mas gift.
Hello, Jen!
I am also searching for fingers for this arm. waiting for your answer
Hello! Im not sure why the files aren’t there.
Please visit our forums and see if anyone else might know what is happening!

Hello,
I am trying to find out where the files for the rit fingers are by any chance? I just need the fingers right before I present my friend his new rit arm. Any advice would be much appreciated.
Thank you

Thank you!!
I extracted the files and IPT files are showing up as Word documents. Of course Inventor can’t open them. Maybe it’s me…otherwise, can someone please direct us to the files?

Hi I am a student looking to print this particular RIT arm design for a student within my school. However, I am having trouble understanding how to get the measurements of the design itself to see if it will fit around his bicep. Is it a “one size fits all” type of design or is there a way to make the dimensions more suitable for this particular student?
Thankyou!
Hello Olivia! Please visit our forums or feel free to email one of our volunteers at support@enablecommunityfoundation.org and one of our volunteers can help!
where can i get the files for the fingers?
Please email support@enablecommunityfoundation.org and let them know that the files for the fingers are missing and you would like to have them! 🙂
What finger design is used for this arm design?
