This is a remix of Clip for Freezer or Snack Bags by Jorge Rui. Please visit his original design and support the designer: https://makerworld.com/en/models/13096#profileId-13090

I really like the original design and I printed a dozen of them for every open bag I had in the house, but for some reason, the original was printing too tight for me and it was hard to loosen up the main hinge. So, I increased the spaces around the hinges and opened the clip to avoid the parts getting stuck.

Now, the hinge is very easy to get moving.
