minifig help

making a 3d printed series for phi-brix
the NUBS
trying to make torso for basic NUBE (basic phi-brix minifig)

its building your character.

I’m having trouble with ball joints and torso.
have any ideas for a torso and ball joints?

Also there are several blendswap models available for “Minifig”, and even more for “LEGO”. Maybe you can download one and start from there ?

If you still have trouble somewhere, please give some details.
