chip-clip
This is a bag clip with a hinge that can be printed in-place without supports. It's very similar to this model on Thingiverse.
I've been using it for opened bags of food (frozen vegetables, chips, etc), as well as to seal a trash bag that's been delegated for used cat litter. Some pictures:

Parameters for a hinge that can be printed in-place without supports!
For the joint angle, the natural response is to set this to something small to decrease the footprint of the printed model, but due to the hinge geometry a higher angle actually makes it easier to print the clip without supports.

The tooth is a triangular feature aligned along the length of the clip.
