This cover cutter works really better than the first one I made in my Nespresso recycling set. And it's not necessary to mount metal blades, just print and use.
You can take a look to the original set here, you'll find useful the other parts of the set, but I recomend you to use this cutter instead of the old one.
To use it fit the tooths bitting the paper and pres with your finger to take the cover.
