pentagram = [

        [round(pt[0]), round(pt[1])]
];

for(pt = px_polygon(pentagram)) {
    translate(pt) 
        linear_extrude(1, scale = 0.5) 
            square(1, center = true);
}

translate([30, 0])
    for(pt = px_polygon(pentagram, filled = true)) {
        translate(pt) 
            linear_extrude(1, scale = 0.5) 
                square(1, center = true);
