I really liked the simplicity and design of LToyCreations filament cutter. However it is a bit small for my hands and I was afraid I would lose it. I built upon their idea by making it slightly bigger, adding shaped areas on each end for my fingers, and adding a loop so I could hang it. Also, I didn't have the correct size spring so I made it work with one I had.

Spring is 3/8 x 3/4 Also added a M3 flat washer. All other hardware is similar.
