Same form factor, with maybe a little wiggle room on the larger board underneath the smaller board. // margins from edges v_margin = hole_dist_top*2; v_margin = hole_dist_top*2 + thickness; col_left = thickness * 1; //right_rib_x = width_mm - thickness*2; // How much horizontal space needed for left-hand and right-hand sub-panels left_panel_width = 12*3 + tolerance*2; // rib + half a jack col_right = width_mm - h_margin; input_column = h_margin; col_right = width_mm - thickness*2; // draw panel, subtract holes union() { cube([board_width, board_height, thickness]); cylinder(thickness+standoff_height, r=standoff_radius, $fn=360); cube([cutout_width, cutout_height, thickness+3]); cylinder(h=thickness+standoff_height+3, r=hole_radius, $fn=360); vertex 0 -8.07502 5.88782 facet normal -4.064186e-001 -7.112327e-001 5.735609e-001 facet normal -3.09121e-05 -0.113324 0.993558 vertex 0.412991 7.35916 6.91579 facet normal 0.634342 0.77296 -0.0119354 facet normal 0.0972815 -0.989353 0.108241 facet normal 0.0761278 -0.0624757 0.995139 vertex 0 8.88682 5.07603 facet normal 0.0994789 0.021876 -0.994799 vertex.
