I found a document that says 30 degrees helical angle is perfect for a herringbone gear. I tried to draw 15 + 15 degrees = 30 degrees ( two helical gears together). Compared to my Extruder gear it makes much more smaller angle "arrow"? What are really good angles? My Repraps Extruder Big gear arrow is something like 50 degrees.
Edit: hmmph I understood wrong how to look the Helix angle. It is 30 on my printer. It was Sketchup that made me understood the angle incorrectly.
