This device is meant to assist in opening plastic packaging with small lips, such as the dried tomatoes bag pictured above. It's intended for anyone with difficulty manipulating small objects.

The current design needs improvement as it has a tendency to tear the bag, but I'm posting as a starting point.

It's sized to fit a flat-top thumb tack / push pin but may need to be scaled slightly depending on your pushpin brand and printer. Put a dab of superglue on the pin head and slide it into place.

I included the Creo design file if you'd like to make changes.
