Summary. Dimensionally the gears are identical to Stoffel15's herringbone/fishbone gears and still a 9:47 ratio. The only changes are a larger number of facets/faces on the parts. So when printed at very high resolution or scaled up, the sides of any circles will not be as visible. I made some minor changes to the scad files to that others could easily change the resolution on there own gears.
