This is a large version of a kitchen sink splash guard.

The faucet opening is 60mm in diameter, which should accommodate most faucets.

This model is 120mm deep, which is designed for deep clearance sinks.

There are two sides to print, the left side will have a small “lip” that creates a lap joint over the right side, preventing leaking down the middle. Glue two halves together with glue of your choice.

If you have a faucet with a surface mount plate (3 hole style) I recommend shimming the sides.
