Beehive Entrance Reducer/Mouse Guard

This is a simple guard that reduces the entrance size of any conventional hive. It can help protect from mice or inter-hive competitors, etc.

I have a smaller Printrbot Simple Metal, so the full length (15.25") wouldn't fit on the board so I divided it up into 3 sub-6" pieces that can be easily and seamlessly be connected.

The guard can also be rotated so that nothing can enter or exit (when you need to move a hive/work on or around it). This is facilitated by the separate connector plate
