Correction Exercise 2:

//Exercise 2

$fn = 100;

translate([0,-20,0]) cube([20,20,2]);

translate([0,-20,0]) rotate([0,-90,0]) cube([20,20,2]);

Correction Exercise 3:

//Exercise 3

$fn = 100;

difference(){

translate([0,-20,0]) cube([20,20,2]);

#translate([10,-10,-5]) cylinder(10,2,2);

}

difference(){

translate([0,-20,0]) rotate([0,-90,0]) cube([20,20,2]);

#translate([-5,-10,10]) rotate([0,90,0]) cylinder(10,2,2);
