Voici le code pour un squelette (sans arc) :

function main(){
    return tout().scale(2,2,2).rotateX(-90);
}
 
function tout(){
    return union (pieds(),
    union(torse(),
    bras()).translate([0,0,-2]));
}
 
function pieds(){
    return union (cube ({size:[1.5,1.5,10]}),
    cube ({size:[1.5,1.5,10]}).translate([3,0,0]));
}
 
function bas_ventre(){
    return cube ({size:[5.5,2,1.5]}).translate([-0.5,-0.5,12]);
}
 
function colonne_vertebrale(){
    return union (cube ({size:[1.5,1,7]}).translate([1.5,0.5,13.5]),
    tete());
}
 
function torse(){
    return union (bas_ventre(),
    union(colonne_vertebrale(),
    ventre()));
}
 
function ventre(){
    return union (cube ({size:[5.5,1.5,1.5]}).translate([-0.5,0,17.5]),
    cube ({size:[5.5,1.5,1]}).translate([-0.5,0,15.5]));
}
 
function bras(){
    return union (cube({size:[1.5,5,1.5]}).translate([-1.5,-3.5,17.5]),
    cube({size:[1.5,5,1.5]}).translate([4.5,-3.5,17.5]));
}
 
function tete(){
    return difference (cube({size:[4.5,2.5,4.5]}).translate([0,-1,21.5]),
    visage()).translate([0,0,-1]);
}
 
function visage(){
    return union (yeux(),
    bouche());
}    
function yeux(){
    return union (cube ({size:[1.25,1,0.625]}).translate([0.5,-1,23.5]),
    cube ({size:[1.25,1,0.625]}).translate([2.75,-1,23.5]));
}  
 
function bouche(){
    return cube ({size:[3.5,1,0.625]}).translate([0.5,-1,22]);
}
