Magnetic Bag Clip V4

About the design

A bag clip (or whatever you call this sort of thing) that uses a notch flexure hinge as its pivot  and a combination of push and pull magnets to provide the bulk of the "spring" strength. This version addresses some frustrations I had with the preceding ones :) This one works pretty well, but don't be surprised if this continues to evolve as I use them and/or get feedback. This design uses 16 (yep, that's right, 16) rectangular magnets - 12x6x3. It's a lot of magnets, but they'ze cheap. I think I bought 100 from Amazon for like $20.
