Water Dispenser Stand

I built this stand to prevent ants from committing suicide in my water dispenser. By creating an island around the support column separated by water , the ants will not be able to climb into the water dispenser. The diameter of my dispenser is 280cm. There are 2 version. 2nd version is slightly raised on the support column for better separation.

Instruction:
Print 3 pieces. Fill in water. Place below the dispenser following the groove of the support column.
