I'm really in love with the design of the "shorty utility knife". But unfortunately there is no cover for it. So i designed my own. You can print it with the same settings as the knife. So choose your infill pattern, increase the perimeters and set the top/bottom layers to zero. Or you can print it solid. Now you can carry around this wonderful knife without cutting yourself or your backpack. The cover snaps right around the knife. Use it like a sheet.
