    Mounting the case to the robot requires 4x #10-32 nylock nuts (placed in the
    hex-shaped mounts inside the case) and 4x #10-32 bolts.

+   Order of addembly of the Orange Pi Double Case matters given tight clearances:
+   1. Super-glue the nylock nuts into the hex mounting holes.
+   2. Intall the fans and grates into the case side.
+   3. Assemble the Pi's into the standoffs outside the box.
+   4. Solder / mount the Voltage Regular solution of your choice.

+   7. Install the Pi/standoff assembly into the case using screws at the bottom,
+      be careful of the tight clearance between the USB sockets and the case opening.
