Like most anime fans, I have a strong appreciation for Studio Ghibli. I first came up with this concept when brainstorming present ideas for some family members of mine, but it has taken me a while to get around to actually designing the models.
For those not familiar (or for those having trouble deciphering my poor artistic rendering of the characters), the dolls from largest to smallest are:
-Totoro (from My Neighbor Totoro, model remixed from https://www.thingiverse.com/thing:12146)
-Noface (from Spirited Away, model from scratch)
-Jiji the cat (from Kiki's Delivery Service, model inspired by https://www.thingiverse.com/thing:948676)
-Calcifer (from Howl's Moving Castle, model from scratch)
I tried to make them with enough tolerance to fit together while still having enough grab to stick together in a sturdy fashion. If you print them out and find they don't fit together, I am including my blender file to allow you to tweak the model easier.
I tried to keep the characters relatively close to proportional, which I was mostly successful with, but Jiji ended up being a fair bit larger than he would be compared to Noface and Totoro.
EDIT: I recieved feeback that the Jiji connection was too loose, so I uploaded 2 additional versions of Jiji's head. One with a .5mm gap, and one with a .35mm gap (for reference, the initial model had a .75mm gap)
