The team behind the original Raptor has released the Raptor Reloaded, an updated and re-factored version of the Raptor Hand. 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. Previously, if a designer wanted to make a small adjustment to a part of a hand, they’d have to rebuild the entire part in their CAD software before they could make the change. Now, they can download the source files and just spend their time making the specific change they had in mind. With this new set of source files, we hope to improve the pace of research and development within the design community.
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 firstname.lastname@example.org for more details.
A portion of every kit sold will go towards supporting enablingthefuture.org 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 Raptor Reloaded hand should be assembled at a similar angle as what is shown here.

Changes in this design include:
- Improved print-ability due to custom modeled supports
- Cyborg Beast compatible sizing
- Improved dovetail geometry
- New tensioner retention clip
- Easier to use tensioner pins
- Low profile elastics with two tie-off options
- More access to elastic and flexsor routing channels
- Debossed versioning information on palm and gauntlet
- Slimmer, more anthropomorhpic fingers
- Narrower knuckle block
- More intuitive assembly (new one-way proximals)
- Thorough documentation and modular design
- Source files in native Fusion 360 format, also STEP and IGES
- Additional velcro-mounting options as well as traditional velcro loop and leather options
- Re-oriented snap-pin head recesses to improve printability
- Knuckle pins are now removable, making the hand easy to repair and upgrade
- Strengthened tie-bars on finger tips
