Ant-Proof Pet Feeder

cults3d

The Purpose of This Pet Feeder Is to Repel Ants from the Food. This Design Utilizes a 2L Reservoir (Discarded Soft Drink Bottle) Filled with Water to Create a Shallow Moat that Ants Will Not Cross Over. Using Salt Water in the Moat May Discourage Slugs. This Design Prints in Three Separate Parts: The Tray for the Water (10.4cm x 20.6cm x 1.7cm), the Bowl Holder (13.2cm x 13.2cm x 3.3cm); and the Bottle Ring (11.7cm x 11.7cm x 3.5cm). You Must Supply the Bottle and the Bowl Yourself. The Bowl Shown in the Photo Is Approximately 12cm Diam at the Bottom of the Tapered Base, and About 16.5cm Diam Including the Rim. To Assemble: Screw the Bowl Holder onto the Tray; Slide the Bottle Ring onto the Bottle; Fill the Bottle with Water; Then Hold the Tray Upside Down While Screwing the Bottle onto the Tray. Quickly Flip the Assembly Upright. Place the Bowl with Food in the Bowl Holder. Concepts: Atmospheric Air Pressure Prevents Water from Leaving the Bottle as Long as the Air Inside the Bottle Remains at Very Low Pressure. As Water Evaporates from the Tray, the Water Level Will Lower and Allow Some Air Bubbles to Enter the Bottle. A Small Amount of Water Will Flow Out of the Bottle Until the Air Pressure in the Bottle is Reduced Again to Very Low Pressure. The Purpose of the Bottle Ring Is to Reduce Deformation of the Bottle as the Reservoir Empties Over Time. The Bottle Ring Helps Keep Your Bottle's Shape Over Repeated Cycles. Keep Debris from Blocking the Water Exit in the Tray.
