This is a version of Ender Dragon by Intentional3D, and its remix by 3D Slash.
I've scaled the combined model from Slash3D to print, but many parts went wrong.
So Ive redesigned and recalibrated most of the model, nullifying tolerances, enlarging ball bearings, rearranging and modifying parts to print more reliably, and got this - that can print in one shot, assemble under pressure and function.
[edited] And now, after a while, revisited and cleaned up the whole thing, after learning a few things. Enhanced the eyes as well. Plus, following great feedback from @Riverrat88_1737528, added another version with built-in 0.2mm brim for thin high vertical parts - columns and long poles. Should enhance stability and allow printing with higher speeds. Brim needs to be cut off after releasing.
Printed white because it glows in the dark. Size can be extrapolated from the ruler in the photo.

Assembly
Assembly requires some force, but mostly - rotate the ball joints before pushing them into their sockets, to shave off the excess material, and rotate them a few times inside as well! the bearings are maxed out in size and should tolerate head & tail weight, but they assemble hard and can break from excessive force when trying to move after clicking them in, if not "shaved" by rotating before pushing.
