Description

Materials and methods

Printing instructions:

Scale all parts as needed (the Raptor Hand is 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, then divide by 55 to get 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 (palm and gauntlet have some supports built into the model)
PLA is recommended
Suggested settings are 0.2mm layer height, 35% infill, 2 outlines
Refer to file names for part descriptions. The number in square brackets at the end of each file name indicates how many copies of that STL file need to be printed for a complete hand assembly.
A video tutorial for the assembly process can be found here: http://youtu.be/5HVwC3RnWXk

Assembling a Raptor Hand requires the following materials:
(4 feet) Velcro, double-sided (2” wide)
(8 feet) Non-elastic nylon cord, 0.9mm
(5 feet) Flexible elastic cord
(5) Tensioner screws
(3) Palm velcro attachment screws with stop nuts
(12 inches) Firm Foam Padding (5 ¾” wide)
(5) Lee Tippi Micro Gel Fingertip Grips (optional)

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

Dear friends from e-Nable!

We've created an assembly viewer for YouMagine which allows you to show a design fully assembled in the 3D view on the design page. This was design specifically so people can share complex designs and still show the relationship between the files and where the printed parts need to go into the assembly. An example is this design: https://www.youmagine.com/designs/pigrrl-zero-raspberry-pi-gameboy

Make sure you also click on the Bill of Materials entry inside the 3D view. You can then see the objects in 3D and the lines that refer to files are actually linked. You can also include and reference non-printable files and indicate that they're not printable (a checkbox). This will become really useful as we integrate useful tools that help people who are printing lots of small objects and who want to keep track of what they have and/or haven't printed.

Feedback:

A photograph showing the e-NABLE badging added to credit the creators of this great piece of 3D printing design.

Result:

Prints really well, the palm is now a much smoother design than v1.0 and prints beautifully without any support. The fingers on this revised design are also much more elegant than v1.0

Feedback:

Printed in ColorFabb Bluish White PLA then painted with flesh colour acrylic paint. The badging was added by printing separate parts using JPEGs imported into Cura. The fingertips have been enhanced by using Sugru (a mouldable self-setting rubber) to provide better grip and control. The Raptor badge on the gauntlet was created with a passing reference to the graphics used on a Japanese superbike.
