This bee watering tray is designed so bees can land and get water from between the hex posts and not drown. It is designed so that a small mouth Mason or Ball jar will friction fit inside the mounting ring.
It does not need support because the bridges are such a short distance.
Yes, I could have downloaded one of the many excellent designs hosted here and other locations, but where's the fun in that? :-)
The author marked this model as their own original creation.
