Update - fixed missing diorama base piece

It was brought to my attention that there was a missing piece for the diorama base (large parts). It seems I didn't notice a floating piece of geometry that got dropped during mesh repairs. I have added a key to this missing piece and added a key to the diorama base (pt1) for any future prints but I have also included a keyless version of the part so that anyone who has printed the diorama base already can just glue it on. The missing piece is now called lady_sin_diorama_base_pt3 and pt3_nokey.
