This is a custom-designed, 3D-printable cover for 3M respirator filters. The cover is intended to protect the filter media from airborne contaminants, dust, and moisture when the respirator is not in use. It helps prolong the life of your filters and ensures they are clean and ready for use when you need them.

The cover is designed to be a snug friction fit with overhanging clips. Depending on your printer's calibration and the filament used, some minor adjustments to the model's dimensions may be necessary for a perfect fit and clean bridging on the initial layer (for aesthetic).
