Buzzer Mount & final rolls of filament guide

Holds a Radio Shack buzzer in a mostly enclosed beehive. Last few hoops of an ending filament roll slips overtop and plays out while roll changeover happens. Cuts changeover time. Enclosure open in rear. Also, buzzer hole is recessed (inside) deeper into baseplate to allow for a few threads on buzzer to secure to nut. M5 Fastener hole is recessed too. Buzzer fires down, (now reflected) alarm seems a little less fierce.
