Mason Jar Lid

I found the original difficult to print as the logo was protruding so it could not be printed with the top of the lid face down. I wasn't particularly bothered about the design so I removed it.

There is also an alternative design which is recessed where the glass meets the lid where you can place an o-ring which I have also included. This helps to create a better seal.

Finally I have included a cutting guide for grease proof paper or whatever other material you wish to use to seal against the top of the glass as PLA/TPU is neither airtight or food safe.
