Thanks Michael, unfortunately I was aware of the little edges so I wanted to know what to do about fixing that. Unfortunately seeing that I can't avoid going across the seam, I am not sure how to best deal with it. However no excuses, I'm still not very prolific in MOI and precision placing and mirror with continuity so I'm sure that attributes to it as well.

Note, I didn't put a fillet in because I couldn't get it to match the 0.5 fillet I have with the rest of the pattern. Perhaps what I should do is model only a pattern portion which could avoid this issue altogether.
