Ball Mason Jar Stacker

thingiverse

This component makes it possible for wide-mouthed mason jars to be stacked neatly. It was crafted specifically with the Ball mason jar in mind, so its compatibility with other brands remains uncertain. The part consists of two halves - top and bottom - which must be joined together using a small amount of super glue after being printed. A few drops are all that is required for a strong bond.
