I've been messing witth this for a good 30 mins now and can't figure out to achieve what I need done.

I have two circles tangent to each other and a space between them I need to extrude, but I keep getting errors, and I can't figure out how to actually draw the shape because the circles are different sizes and not sitting near any midpoints.

I would be extremely greatful if someone could show me how I can extrude this space in this model.

Sketch4 contains the circles I'm working with, the empty space between the circles and the "peg" needs to be filled in so the peg itself is not just a straight peg.
