```openscad
innerW = 20;
innerL = 20;
height = 10;
thickness = 3;
module rounded_box(l = 20, w = 20, h = 20, r=2, fn=32) {
linear_extrude(height=h) {
offset(r=r, $fn=fn)
square([l-2*r, w-2*r], center=true);
}
}
difference(){
//outer box
rounded_box(l = innerL + thickness, w = innerW + thickness, h=height);
//inner box
translate([0,0, thickness]){
rounded_box(l = innerL, w = innerW, h=height);
}
}
