Hi niko - the easiest thing is to not worry about it - if you are manufacturing this part there is no way that tiny level of detail is going to make it into the end result.

Otherwise if you want to get a smooth result between pieces you need to use Fillet or Blend to generate continuous surfaces, other techniques won't work.

Or also you might want to use Rhino and try the MatchSrf command in Rhino which is an editing tool that adjusts an untrimmed edge of one surface to be smooth with another. It could help you in this kind of situation.
