This is a variant of the cutter guide with a sponge that allows you to clean the cut strip from dust and residues. Cut a piece of a sponge so that it fits into its slot and then make a cut along the pass line. The guide is removable from its backplate.

I made it for my Vertigo version ( https://makerworld.com/en/models/103692 ) but it can also be mounted on the original version.
