It's easy enough to remove the flange in the model, and print them without it, but, it's such a small part, with very precise details, and I wouldn't want to decide for the end user whether to leave just a touch/hint of the flange, or have it be smooth and flush, etc. Everyone has their own idea in their head for how the chunk should look, I'd think, so any replicas, I believe, should leave all options open to the end user.
That said, are you saying you want a version with just a hint of the flange remaining, or completely flush?
