I had trouble slicing Okatake's stl files with Kisslicer, so I figured I would make my own. :) It is not a direct copy; I've modified the end height to more directly match the original large gear, and reduced the height of the actual herringbone so it is just slightly shorter than the original v10 gear. I'm in the progress of changing the gear profile, as the current one seems to be a bit weak, and the outer edges of the teeth have broken off. It still drives fine, but I'll see if I can make it any better/stronger.print as normal. drill holes to size (5mm and 4mm). fit as normal.
