The Raptor Hand by e-NABLE

youmagine

The objectives in creating the Raptor Hand were designed to achieve several key goals: * To simplify fabrication, assembly, and repair for makers and recipients alike, ensuring a seamless experience from start to finish. * To provide a platform and reference design for future innovations, whether incremental or radical, giving users the freedom to experiment and push boundaries. * To identify a core feature 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. The Raptor Hand by e-NABLE builds upon these classics with several exciting new features: * Easier and quicker printing, eliminating the need for supports and streamlining the process. * Easier and quicker assembly, featuring simplified cord installation and no Chicago Screws required. * An improved tensioning system, boasting a modular design that allows for easier future development and customization. * Improved documentation, coming soon to provide users with even more resources and support. All of the parts needed for assembly can be easily sourced in most areas, but for those who prefer convenience, 3D Universe offers kits containing all the necessary assembly materials: http://shop3duniverse.com/collections/3d-printable-kits/products/raptor-hand-by-e-nable-assembly-materials-kit Printing instructions are as follows: * Scale all parts as needed, with the Raptor Hand designed to work at scales from 100% through 170%. * At 100%, the inside of the palm area measures 55mm. * Measure across the widest part of the palm, then add 5mm for padding, and divide by 55 to determine the scaling factor (for example, if the palm is 65mm wide, then 65 + 5 = 70, and 70 / 55 = 1.27 - so your scaling multiplier would be 1.27 or 127%). * Print without supports, as they are built into the model for the palm and gauntlet. * PLA is recommended, with suggested settings including a 0.2mm layer height, 35% infill, and 2 outlines. * Refer to file names for part descriptions, where the number following the "X" indicates how many copies of that STL file need to be printed for a complete hand assembly. * After printing, remove the built-in support pieces from the palm, gauntlet, and dovetail cap.
