effort travel residual
Each pose is derived, not drawn: the fingertip is pushed one switch-travel along that action's own direction, and the joint angles come from the pad Jacobian — the same one the effort model uses. Residual is how much of the required joint torque the muscles fail to produce; 0% means the digit can really do it. The gauntlet is drawn at the radius the physics chose for each strut — thick where the load runs, thin where it does not. The members are hollow tubes — the wall is drawn translucent so you can see the marrow cavity inside it. 95% of them are as thick as they are because a hand has to bear them, not because a force demands it, so the inside was doing nothing and came out: −19% mass, identical to the touch. Show supports draws every column the printer must run up from the bed and you then snap off.
