It is the same as the hex version of Dust filter cover for 3M mask by vyrobca (https://www.thingiverse.com/thing:3982639) but shortened. In the foto you see the original design. I had to cut off part of the rim, because it would collide with the 3M 7502 mask. I am using it with this https://www.thingiverse.com/thing:4215903 or better the remix https://www.printables.com/model/358166-3m-603-filter-adapter-to-use-ffp2-masks (support is easier to remove).
