Hopefully in a future version of the Pi Zero, the CSI clasp can be better designed. If a girl can dream - maybe it could be the same clasp as on the camera board!
EDIT: If I were to hot glue my clasp shut on the ribbon, where would be the best/safest place to glue? A (the ends of the clasp), or B (the center of the slot)? (See image) Do I have to worry about the glue seeping into the cracks of the CSI slot and damaging the parts?
I have to say, I've probably had to re-insert the ribbon into the Zero's CSI slot many hundreds of times over the course of my project, it is so incredibly easy to come loose and so difficult to secure. It seems to work exactly opposite from how you would hope. When I pull it open, the slightest touch bumps one of the two sides closed. When I insert the ribbon, it's nigh impossible to get the ribbon evenly and fully inserted into the slot - there's no locking mechanism like there is on the camera-side's ribbon clasp. If I do manage to get the ribbon fully inserted into the slot, it's finger gymnastics trying to close the clasp on both sides without one side of the ribbon slipping loose - I need to hold both sides of the ribbon to keep it fully in the clasp, another hand on the Pi to keep it stable, and more fingers to try to jam the clasp closed (at this point it magically becomes very difficult to close, while it closes seemingly of its own accord when there is no ribbon in it). After all this is done, the slightest touch or a light breeze, and the ribbon is fully out of the Zero's slot again.
