Flip Top for Wide Mouth Mason Jars

thingiverse

I've been working on this flip top for a while now and have been through a few revisions to get it just right, I'm still working on a similar top for a regular mouth jar. This top will fit a wide mouth mason jar and will replace the sealing lid and still use the screw-on ring. If you're printer has a smooth bed you can get away without a gasket, but if needed a small bead of silicone around the bottom edge works well. My printer is able to bridge fairly well so I didn't have to use any support material on the cap. Depending on your printer, support may be necessary under the cap. Instructions Print a Lid and a Cap and press the tangs of the cap into the lid. If your printer doesn't have a smooth bed you may need some silicone to create a seal between the lid and the jar. Can be printed without support material if your printer is fine tuned well enough to bridge a small gap.
