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://www.printables.com/it/model/388260-recreator3d-vertigo-by-mz3d-printer-filament-from-) but it can also be mounted on the original version.
The author remixed this model.
