base_height = 8;
upper_height = 5;
wall_thickness = 0.4;
upper_wall_thickness = 1.2;
filepath = "/path/to/your/shape.svg"; // reccomend using absolute path names

module shape(offset_amt=0) {
    offset(offset_amt)
    import(filepath);
}

difference() {
    union() {
        linear_extrude(height=base_height) shape(wall_thickness);
        translate([0, 0, base_height]) linear_extrude(height=upper_height) shape(upper_wall_thickness);
    }
    translate([0, 0, -1]) linear_extrude(base_height + upper_height + 2) shape();
}
