These are designed for TPU flex

There are two sizes of carafe lids provide based on the ones I own. 

There are two styles here.  Both Generated with the TPU can lid generator :

1. Angled Edge
2. Square Edge

You can make your own using the TPU can lid generator

I was asked to make the lid easier to get off.  I added a tilt-out entry edge.  I did this one manually.  I will add it to the code generator.  It makes the lid easier to install and remove.
