High Quality Water Bowl for Pets

Update 6/22/2026:  Added an adapter that fits 3L PET bottles.  No supports required.

Update 6/11/2026:   Added an adapter so that you can now use PET bottles (1L water, 2L soda, etc.). 

Adapter Notes:  If water leaks past the PET bottle threads, you can apply some thread sealant or thick glue into the threads to fill in tiny gaps.  Let the glue dry with your PET bottle screwed into it.   The models are pretty accurate, but it is difficult to get a water-tight seal with 3d printed threads.

A sleek and minimalist gravity-fed pet water dispenser designed for both style and function. Featuring a modern two-tone design and smooth 3D-printed finish, this dispenser automatically keeps your pet’s water bowl filled using a simple gravity flow system. Compact, easy to refill, and perfect for modern homes, it provides a clean and convenient hydration solution for cats and small dogs.

Recommended print settings:

• Orient the bowl in a diagonal fashion on your build plate to help it fit

• PETG 

• 4 walls minimum 

• Minimum of 5 top and bottom solid layers

• 0.2 layer height (due to threads) or use the adaptive layer height feature

• SPEED LIMIT:  Print solid infill and inner & outer walls at 100mm/s or less
  to help ensure a good water-tight bond

• Infill doesn't necessarily matter much, but I went with 20% Triangle pattern with 2 lines

• I recommend a transparent PETG for the tank.   It gives it a nice look and helps you see the water level too.   Any color PETG for the base is fine.

I've included the STEP file in case you want to tweak something in CAD and remix.
