Wide mouth mason threaded jar lid (86mm)

I took the lid stl from thing:478811 and found I needed to shrink it to 94.8mm in diameter (starts as 96mm) to get the tight fit I was after. I used Cura's Scaling tool to do this uniformly meaning the Z was also reduced.

I then used Autodesk123D to add a plate and ring "into" the lid as well as some ribs. I prefer bumps to indents. I also added a size label since print a lot of lids.

Nice tight fit. I haven't tested if you can flip it upside down though.

Kept the original designer's licensing and I make no claims to this design as my own.
