The Phoenix Hand is available in several different versions:
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.
For users without a functional wrist, please refer to the Unlimbited Arm, which also incorporates the Phoenix Hand design.
Phoenix Hand (Original)
Files for Phoenix Hand (Original)
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.
This is a remix of the original e-NABLE Phoenix hand by Jason Bryant with replacement components by John Diamond, Scott Darrow and Andreas Bastian. The changes from the original are as follows:
– Gauntlet – Original fully 3D printed version replaced with a thermoformed equivalent (lighter, stronger, uses less filament, quicker to print and can be adjusted to better fit the forearm)
– Gripper box components – Whippletree doesn’t require tying to the swivel pin using string. The printing support from the swivel pin should be cut/snipped/filed off before assembly. The thumb tensioner pin is shorter so it doesn’t need to protrude from the front of the gripper box.
– Thermoformable palm mesh – An easier to assemble alternative to using Velcro in the palm. Can be thermoformed and adjusted to fit the recipient. Two alternative versions, thin/thick, are provided.
– Palm with supports – The support structure uses less filament than the original and can be easily, safely and cleanly removed by hand usually without tools.
– Demo bar – Used instead of the palm mesh if the hand is to be used for demonstration purposes. It allows a person with a full set of fingers and thumb to wear the hand and operate it.
– Wrist pin – This pin has been shortened to allow it to be used with the thermoformed gauntlet.

Files for the Unlimbited Phoenix
The Unlimbited Phoenix design is the easiest version to print and assemble. It includes a more comfortable reverse dovetail thermo-formed gauntlet, and a cleaned palm devoid of holes which uses a thermo-formable mesh. The palm mesh is integrated directly into the palm, unlike the previous versions that require 13 screws to attach.
This design takes advantage of the Thingiverse Customizer, making it very easy to get the parts for printing in the desired scale. Just choose left or right and set the slider in the Customizer to the desired scale percentage, and you’ll receive a ZIP file containing all of the parts needed at the correct scale.
Files for the Phoenix Reborn
This is a remix of the Phoenix Hand & UnLimbited Arm, designed by Albert Fung. This project is a collaboration between e-NABLE Sierra Leone and the Hong Kong Maker Club.
It became apparent in our previous feasibility study that for the 3D printed prosthetics to survive the tropics, we need to remove components that are not well-adapted to hot weather. We therefore set out to replace all the rubber bands in the Phoenix Hand.
Palm: We used the One-Arm palm designed by below_cho as our starting point. All the cable tunnels have been widened, the knuckle stumps removed, and a bar is added at the thumb base for tying elastic cord.
Palm mesh: we have modified the thick palm mesh by John Diamond to strengthen the screw holes.
Fingers: Tunnels have been created so an elastic cord can now run all the way from the fingertip up into the palm.
Pins: For snug fitting, some of the pins have been resized and reshaped.
A kit containing all of the assembly materials needed to build any of the Phoenix designs can be obtained from 3D Universe.
