This device is intended for users who have difficulty removing the seal on a canned jar. This works for both mason jars as well as one piece lids.
To use the device, place the bump on the end on the lid of the jar, and place the hook under the edge of the lid. Lever the handle of the device upwards and the lid will come off.
After printing the STL file, remove all supports, and sand any rough edges.
