Largest 3D printed item thus far: a 10 hour print that worked without glitches; what an accomplishment!

designed in OpenSCAD:

difference(){
for ( i = [0:5]){
	intersection(){
		translate([-75, -75, 3 + 20 * i]){
		cube([150,150,40]);}
		translate([0,0,50 + 20 * i]){
		sphere(r = 65 + 3 * i , $fn=11);}
	}
}


translate([0, 0, 82]){
	cylinder(r1 = 40, r2 = 76, h = 150, center = true, $fn = 11);}
cylinder(r = 20, h = 40, center = true);
}
