This is my cheat method. This torso uses the same principle as my Minecraft head floor. It’s as strong as BricksofAwesome’s design if you add open 1x1 round plates to the hose to reinforce it.
It’s fully adjustable and breaks lego’s grid system depending on the length of hose. You could even adjust it to exact human proportions if you wanted to.
The chart above is scaled precisely to a Toa Mata head. As you can see, the shoulders are a tad too wide and the trunk is way too short, but that can be adjusted with different hoses.
Ideally, you’d use a bigger chart since lego pieces are too large and imprecise to work at this scale. Human contours are too finite to achieve with lego, so this chart is really more an approximation than anything and I wouldn’t follow it too closely.
But yeah tl;dr you can get close to human proportions if you “stretch” ccbs torsos with this method.
