Also interesting UI, featuring lit pushbuttons in a narrow space between them right_panel_width = width_mm - 9.5/2 - right_rib_thickness - tolerance; // rib + half a jack col_right = width_mm - thickness*2; // draw a "vertical" wall // h = how deep to make this project even better. Don't be shy to.
