 }
 translate([0,4,0])
  cylinder(r=2.5,h=2, $fn=20);
 translate([-3,-37,0])
  sphere(r=1.4,h=1, $fn=20);
 translate([-3,-31,0])
  sphere(r=1.5,h=1, $fn=20);
 translate([-3,-26,0])
  sphere(r=1.1,h=1, $fn=20);
 translate([-3,-20,0])
  sphere(r=1.4,h=1, $fn=20);
 translate([0,-41,0])
  rotate([-10, 0, 0])
   #cube(size=[4.8,40,2], center=false);
