Flip Top for Regular / Small Mouth Mason Jars

Similar to my flip top for a wide mouth mason jar http://www.thingiverse.com/thing:534800 I've now designed a top to fit a regular / small mouth mason jar.
This top will fit a regular / small 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.
