3D Print of DRAGON QUEEN *IN AIR* (Small printer size/ 370mm tall-280mm wide)

i am having an issue with this print, the small piece that goes between the main body and the rear end dont fit together. the bit sticking out of the rear end that goes into the smaller part, it WAY to long, this was on the Lychee supported files. i though i was missing a print but im 100% sure i have 1 of each, you can see in the photo where it is bottoming out and rubbing against it.
