>>6628749I shave the parts in red with a hobby knife, very slightly, test if it moves smoothly, if not, shave a bit again.
You can fuck it too, I shaved too much of my Innocentia pigtail joint and now it falls easily from her head.
I guess you can fix it with putty but I've decided to remove the pigtails so I haven't tried.
I also do it with the connectors of every part so that I can disarm them easily. I do this thinking I'll buy plastic glue someday to erase the seams or paint the models. Maybe I never will but I like being able to open easily all the parts.
