Double Ended Jar Ring - Join Two Jars - 3 Versions

thingiverse

I took scootercommuter's Wide Mouth Jar Ring and gave it a major overhaul so that a jar can be screwed in from both ends. The sizes of the jars can vary, depending on your needs, as long as they are both wide mouth mason jars. There are several innovative uses for this adapter: 1) Use WITHOUT the jar's metal lids to store items too tall to fit in a single jar, like uncooked spaghetti. 2) Use WITH the metal lids as a lunch container with different food items in each end. 3) Use WITH the metal lids as a container to store small items in each end, like nuts and bolts or different sized screws. 4) Use with sealed canning jars for space saving and stability when stacking in the cupboard. 5) Use WITHOUT the jar's metal lids as a mini greenhouse with dirt in the bottom and a glass dome on top. UPDATE: I added a Double Ended Regular Mason Jar Ring, giving you more options to work with. I also created a Double Ended Combo Ring - Regular on one end, Wide Mouth on the other. These latest additions were inspired by AlexEnglish's canning jar lids.
