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
