Screw Jar Lid for Pint or Half Pint Wide Mouth Ball or Mason Jar

I'm working on some non canning designs which require that a screw lid which mates with a standard mason or ball jar. I printed a number of the existing thingiverse designs before deciding that I needed my own accurate base model for my subsequent designs. I'm putting this base model up because it's useful, as is, in it's own right.

NOTE: ADDED Original Solidworks 2014 design file as well as STEP and Parasolid.
