Unlike the front and left side gables, the chimney gable on the right posed problems with the gable trim. The chimney sticks out further than the roof edge and therefore blocks the space where the gable trim is intended to be.
The gable trim’s tabs should align with the slots on the roof.
Whenever I have a situation like this, I try to find at least one real life example of a solution. In this case, I found one from Eastern Kentucky University. This shows the gingerbread trim added on either side of the chimney. Works for me! And, yes, had I thought this through earlier, I might have made adjustments to the roof boards, the chimney or both.
I lined up the whole gable trim piece with the chimney in place (but still removable). I marked the break on the main part first and made a few cuts to get a good fit. I had to adjust the tabs on the gable trim to fit better. Once I had that portion figured out, I measured and cut the smaller piece on the other side. Success!
