teeth, head and eye blanks, scaled to 1800% or about 200mm
jaw to 1900%
be sure to check everything fits right and if you have a larger head scale them up more.

I printed this in TPU with no walls at 13% infill with connect infill lines on, if its off turn it up a little, and use with gyroid infill.
if it jams try slowing the printer down and turning off reaction.

I did servile test print to determine with infill to use

since its a moveing jaw I used mesh modifiers in the slicer, making the spot around the hinges have regular walls at 20% infill and drilled holes
I also added a solid part to the bottom edge of the jaw for rigidity but its not supper important.

note it needs a lot of supports and since its TPU they are a pain to remove, I used some eaxto knifes to do it but stull had to be careful not the tare parts of the base.

the cube is not part of the base it self, it can be used as a infill test and or mesh modifier.

and if you use blender and want to modify it I included the .bend file to.
