The associated CAD files will require slight modifications if you have a different OD on the round stock you are attempting to cut. However, the overall design worked flawlessly during my work-holding setup. The only change I would consider would be to overhang the front of the machine a bit more so that the 2 top pieces of the vise jaws could mount under the lower 2 pieces (gains more Z-axis movement, but also comes closer to maxing out the Y-axis movement)
