Frame Arms style torso for Carbon 13 Type F

The new Carbon 13 figure is great, but the exposed connector in the torso was bothering me in an otherwise completelly smooth figure. So I decided to adapt the torso from the Frame Arms compatible kit I had published previously, with several improvements to printability and toughness. 

My version retains most of the articulation of the original torso, and has the same as the Frame Arms kit, but now the belly joints are hidden inside the body, creating a much smoother and realistic figure. 

One of the images show how it's put together, the trickiest part is the pelvis, as you have to snap the groin joint to the lower connector and the pelvis to the lower belly at the same time. 

The two belly parts must be joined with two pieces of filament, a dab of glue is recomended but not required. there's a version without the cut on the optonal parts, that one should be used with the optional pelvis and the legs connector mounted underside.
