This was inspired by a carabiner type clip that would tend to open when and force was applied. The idea is that the tendency to open works in both directions and should draw the clip back closed. It may require some breaking. Printing at the current size did not for me but printing at 2x produced a much better clip in my opinion. I think a definite way to improve it would be to make the top-end triangular rather than round. Also, I need to find a way to add a bit more mass to the side which is tapered (which was done due to printing limitations.
