Drinking fountain for cats
thingiverse
Does your cat really like to drink from the tap? This automated drinking fountain mimics a tap without wasting water. I designed a bowl and a pipe to connect it to a water pump, which is connected to a PIR sensor that activates the pump when the cat is nearby. Parts: - Bowl: Designed to hold the water pump and a support for bottles. Feel free to redesign it and improve it. - Pipe: A 1.5mm-thick pipe. - Support for bottles: Based on thing #38224, which includes a female helix to connect it to the bowl for using different pieces with various bottles. UPDATED V2: I kept the original height to ensure the water level at the pump's entry. - Support for 9 volts battery: Thing #2672627 was used. - Switch: A small switch to turn the system on and off.

See the electrical diagram in the pictures. This is my first design.
