The Infinity Bowl is my in-wall pet feeding and hydration build. It combines printed parts, water and drain plumbing, ultrasonic sensing, solenoid-controlled flow, LED feedback, and a pull-out drawer for service access.
I built it around a basic pet-care annoyance: water bowls get dirty, refills become background work, and spills end up where you do not want them. This version moves the water path, electronics, and service access into a fixed wall station.

Printables model
This is the Printables page for my Infinity Bowl model. It has the model files, printed-part photos, CAD views, assembly images, finished installation shots, and contest context.
What it is solving
The project connects to household cold water and a dedicated drain instead of using a removable reservoir. That lets the bowl bring in fresh water and route overflow or waste water away from the floor.
Water and safety path
An ultrasonic sensor detects when a pet is present, a solenoid-controlled path brings water to the bowl, and a custom acrylic faucet uses light as an active-flow cue. The drain and overflow path are the part I cared about most, because a smart bowl that leaks is just a more complicated bad bowl.
Drawer layout
The valves, wiring, printed brackets, bowl geometry, and service access live in a pull-out drawer. That keeps the front clean while still making the guts reachable when something needs adjustment.
Electronics and software
The electronics layer is Arduino-oriented: sensing, valve control, indicator lighting, saved settings, and a small dashboard-style monitoring surface. It is part printed model, part plumbing project, and part embedded automation build.
Overview video
The project was entered in Printables' Smart Pet Gadgets with Arduino contest, where the listing records a third-place result.
