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

This small version should also be suitable for bathroom sinks.

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

This model is 60mm deep, which is designed for short clearance sinks (like my mom's, pictured).

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.
