Snapmaker U1 has two grilles with large holes on the inside floor of the machine and a habit of throwing bits of purge outside of its bin. These guards reduce the hole size to prevent debris from falling inside.

Color match for stealth cleanliness or personalize your printer with a pop of color. The hole patterns is the same for both grilles.

This is modified from Cryostatic's design (which has since been delisted) for better fit.
