Beehive legs that block ants from getting into the hive.
You'll probably need to print 4 of these (one for each corner of the beehive stand). If you print them mostly solid, the legs should come out very strong so that they can support the weight of a full beehive BUT be sure to test them before using them on the hive.
If you decide to permanently attach the legs, each one will just need a screw and washer to fasten it through the center hole and into the wood of the beehive. After leveling your hive, you can add water, oil or some other substance into the moat of the leg. That'll block ants and other crawling insects from marching up into the hive. The legs will need to be checked periodically to make sure something isn't laying across the moat or that the ants haven't sacrificed themselves as bridges for the colony.
I've included rain caps that go over the legs to keep rain from washing away the oil or water you put in the moat. They can be removed to clean or refill the moat.
