Constant Problems trying to Print DnD minis

Hi, I'm new and just needed some help. Everytime I try to print these dnd minis which I make by springing together various stl models (thingiverse), the print doesn't seem to be able to finish properly, instead the predictive software I use (Ultimaker Cura) shows that the filament doesn't follow the STL files of my models and seems to only go through very few layers. I use blender to edit and alter my stl files and ultimaker cura to check the filament possibilities. I would like some assistance, because I'm not sure what I'm doing wrong. For sizes, I'd prefer it if they could remain the same size as my model (Archer 3.2 cm, Dragonborn 3.3 cm). I tried to upload the stl file, however, unfortunately, the size is much larger than the 19MB limit (55MB). Thanks in advance for any help you can offer.
