***06/12/2017 - Getting requests for smaller sizes. I have changed minimum Bicep size from 160 to 110, but cannot make the hand smaller! 135 is the minimum for two reasons. Firstly the safety of the children (choking on small parts), and tolerance/weakness of small pins.
***17/07/2017 - Receiving feedback that the pins are too long to insert in cuff tensioner box easily. The Cuff minimum has been reset to 65mm to fix.
***14/03/2017 - Update v2.1 Rounded cuff edges, refined palm. Version / Measurement A B C / Hand scale% now stamped on underneath of cuff for reference.
Team UnLimibited are very proud to release version 2.0 of their UnLimbited arm design; named the Alfie Edition after it's first recipient.
The UnLimbited Arm 2.0 is fully parametric and customisable using Thingiverse Customiser to produce all the files correctly scaled based on a recipients real world measurements.
This is the next generation deviced based upon the popular 1.7 Isabella edition that was released last year as found here :- http://www.teamunlimbited.org/the-unlimbited-arm/

We would like to give a BIG thank you to the following people for their advice and help on this release.
Steve wood AKA Gyrobot for his ongoing support - http://www.gyrobot.co.uk/
Tony Buser from Thingiverse for his advice on customiser.
Jen Own from Enabling The Future for her continued effort to blog the activities of the e-NABLE community - http://www.enablingthefuture.org/
We also like to thank the e-NABLE community and Everyone else who has helped support us over the last year so we can keep giving the world a helping hand; or arm in this case !

We print using Simplify3D,
The Palm Area and the Cuff need support when printing; NONE of the other parts do.
For the Palm we typically add 2/3 rows of support in the middle of the palm area to help with bridging.
For the cuff we use auto generated support.
ALL parts are printed in PLA to allow for easy thermo-forming.
We suggest the following additional print settings :-
3 Perimeter shells, 3 Top and 3 Bottom Layers.
The Unlimbited Arm V2.0 - Alfie Edition is the successor to the previous Isabella Edition arm released by Team UnLimbited last year.
Key Features :-
Arm is now 100% Parametric and can be scaled to ANY recipient size, with only constraint now being print plate size (were working on fixing that as well)
Using real world recipient measurements Thingiverse customiser will generate ALL required components pre-scaled to recipients size.
- Massively simplified workflow to build an arm.
1 - Measure recipient
2 - Use Customiser
3 - Download components
4 - Print
5 - Assemble
6 - e-NABLE the Future !
Taking Recipient Measurements
In order to build and UnLimibited Arm the following measurements are required.
The length of the NON-AFFECTED hand as measured from the wrist to the end of the longest finger. Shown in the Diagram as measurement C.
The length of the NON-AFFECTED forarm as measured from the inside fold of the elbow to the wrist. Shown in the Diagram as measurement B.
- The circumference of the AFFECTED upper arm, measured from the middle of the upper arm; Shown in the Diagram as measurement A. TAKE NOTE thats the AFFECTED arm you are building a device for not the NON-AFFECTED arm the other measurements are taken from.
Now that you have the measurements for the device you need use customiser (from the button on the right of this page)
Enter the measurements into customiser using the drop down box and the slide bars and click Create Thing.
Once processes in "My Things" section you will be able to access and download all the files you need for your generated UnLimbited Arm.
N.B. If previewing the Phoenix hand elements of the arm you will not see these scale in the preview box, but trust us the end files will be re-scaled as per your measurements.
Assembly of the arm is the same process as that of the 1.7 Isabella edition, using thermo-forming. This has been previously covered in our 1.7 video and is provided below.
Why We Do This
Below is a video showing why we do this, using 3D printing to bring smiles to those with a limb difference.
Why others do it
Please see a video about a 10 year old boy called Henio from Poland his arm was produced by Krzysztof Grandys who created this arm using this thingiverse design and customiser.
