Shaving Razor Protector

This is a slide-on protector for shaving razor blades. It doesn't need supports (if printed vertically), and is a snug fit. I buy my refills in bulk which means when I travel, I either don't have anything protecting my razor blade, or I have to take the huge case that comes with the refill packs. This solves that problem and allows me to separately pack the razor blade and the handle so they fit better in my travel bag.
