find the assembly order so that it reaches the latch on the bottom of box [right_edge, -extra_depth], // bottom horizontal rib h_wall(h=4, l=right_rib_x); // middle-bottom h rib // h_wall(h=1.6, l=right_rib_x); // middle-bottom h rib // h_wall(h=4, l=right_rib_x); // middle-bottom h rib // middle horizontal rib // h_wall(h=4, l=right_rib_x); // one more to mount the circuit board to, dead center // one more to mount the circuit board to, dead center // one more to mount the circuit board sideways on HP = 5.07; // 5.07 for a 1uF capacitor. 1uF may be brought only in 1000+ for these.
