The Raptor Hand by e-NABLE

PLEASE NOTE: While the Raptor Hand has been a very popular design for the e-NABLE community, it is no longer recommended for use, other than for testing/research purposes. Testing has shown that the gripping capabilities of this design are not as good as more recent e-NABLE designs.

UPDATE, 4/3/2015: Updated finger snap pins (DistalPins2 [x1.stl) for tighter fit. Replaced the gauntlet with new parts, now called "Bracers". Five different shapes of bracer are available (type A-E).

UPDATE, 3/30/2015: Updated distal phalanges to include stronger tie-off bars.

UPDATE, 11/1/2014 : The elastic tie-off bars have been removed. The elastics now tie-off at the upper rear portion of the palm, right above where the non-flexible cords feed through to the tensioner pins. See photos for details.

We are very pleased to introduce the Raptor Hand by e-NABLE, designed collaboratively by some of e-NABLE’s top designers!
The Raptor Hand is intended to bring together the best and most widely tested ideas from a year of crowd sourced innovation.

The objectives in designing the Raptor Hand were as follows:

• To simplify fabrication and assembly and repair for makers and recipients alike
• To provide a platform and reference design for future innovations, incremental and radical
• To identify a core features set and standardized dimensions embodied in accessible 3D models with progressive licensing terms that will ensure widespread availability and future development.

e-NABLE's prior "go to" designs included the Cyborg Beast, the Talon hand, the Ody hand and the Talon Beast. To these classics, the Raptor Hand by e-NABLE adds the following features:

• Easier and quicker printing (no supports required)
• Easier and quicker assembly (no Chicago Screws required, simplified cord installation)
• An improved tensioning system (modular design, allowing for easier future development)
• Improved documentation (coming soon)

All of the parts needed for assembly can be found easily in most areas, but if you prefer to get everything in one place, 3D Universe offers kits with all of the assembly materials needed for producing a Raptor Hand: http://shop3duniverse.com/collections/3d-printable-kits/products/raptor-hand-by-e-nable-assembly-materials-kit
