thingiverse

Here is version 3 of the variable hand grip tensioning box that I am developing for the e-NABLE Raptor type hands. Here is a video of this hand in action: https://youtu.be/oHB3XCw9yUs Please see the following link for information on version 1 that I reference in this video: http://www.thingiverse.com/thing:890953 This version is half the height of version 1 with the same effective action. Two original cams have been placed side by side and 180 out of phase to each other. The finger strings run under the first cam and over the second cam. The knob is connected to the two cams via gears, allowing them to be placed into four unique positions that cause four different grips.
