Bee Hive Entrance Disc

thingiverse

The ideal entrance size is around 45mm based on Tom Seeley's work, this allows for fully open or partially open, use the slot with landing board for a reduced colony and easier to protect, or close entirely or use the vents. this is suitable for any horizontal hive or vertical hive with a round entrance, use 3 of them on a horizontal Layens hive which is what I have. Despite what you may read PLA is very durable outside, I've had parts exposed to the full extent of the weather for years now without issue. Use a 5mm screw to secure the disc directly above the entrance and rotate the disc to align the desired entrance.
