Summary This is a variation of my OTHER Machine vise. Modified base halves for Nema 14 mount. Includes also a modified Center Gear. The remaining parts (sliding jaw, jaw plates, threaded rods, threaded gears, pins) are from the original vise. It also works with the modified threaded rods: http://www.thingiverse.com/thing:2123529. Since their pitch is 4mm and the regular rods have 1.75mm pitch, the clamping force will be less, but the jaw will move faster. The clamping force also depends on the current from the stepper driver.
