Ant Moat - Hào bảo vệ tách cà phê khỏi kiến

This a moat for your coffee to defend it from ants and other crawly things. It prints without support. I used PLA but any rigid filament should do fine. Fill the 'moat' with water and add a few drops of liquid dish soap; this breaks the surface tension so critters can't float. The moat holds enough liquid for about two days before it needs refilling.
