One-Handed Can Opener

pinshape

Try opening a jar one-handed sometime. I doubt you have. Go ahead, give it a shot. How did that work out for you? 3 pieces make it easy to print and store, no need for supports or mounting it permanently, can be easily scaled up for larger or smaller jars. Just place it on the counter and use your body weight to push down on the plunger, opening jars and cans with ease every time.
