I wanted the branches to sit flush when they were seated on another branch. The main branch area is thicker so that it can still print without supports. When you stack branches they sit completely flush now. Also made sure that dimensions for the stud areas (internal and external) is compatible with the original dimensions so other add ons should work without any modification to size.
The leaves printed in pink show the original where there is a gap from the one above to the bottom, the ones printed in dark green are my remix version showing how it sits flush against the one beneath it.
The author remixed this model.
I wanted the branches to sit flush when they were seated on another branch. Tweaked the dimensions for thickness of the main branch structure, and internal and external dimensions of the diameter of the leaves (pips).
