Mason Jar Wide Lid with Slider

Share this:

This design won us Cults3D “Selected Designer” badge 😉

I use this jar for my dog’s treats but of course, you can use it for anything you’d like. I’d like to be able to quickly open the jar and pour the treats out.

This mason jar lid fits mason jars that use wide-mouth lids. There are 3 parts to this. The jar adapter that connects to the jar, the slider (blue in the picture), and the slider housing. See assembly instructions below to make sure you get it right in the first try.

Raft / Support / Glue: Not needed

If you need one that fits standard lid mason jars, we got you here.

Assembly Instructions

Step 1: Hold the slider housing (white), thread side up. Place the slider (black) inside the slider housing, aligning the slider notch with the slot.

Step 2: Put the LIP part (!important) of the jar adapter (white) on the slider (black), thread the jar adapter into the slider housing.
