@arneboockmeyer nice job. Added ability to center in x, y and xy axis

module rounded_rect(l, w, r, center=false, xcenter=false, ycenter=false)
{
    translate([((center || xcenter) ? -l/2 : 0),((center || ycenter) ? -w/2 : 0)])
        translate([r, r])
            offset(r=r, $fn = 60) 
                square([l-(2*r), w-(2*r)]);
}
