Cap for Abbott CustomFeed bottle

This is a replacement cap for an Abbott CustomFeed 60 mL breast milk storage bottle. The picture shows this model (pink) compared to an original cap (white).

I added a plug that makes snug contact with the inner surface of the bottle. This should make it somewhat liquid-tight. There are two versions, a 34mm plug (regular), and a 34.5mm plug (tighter).

The entire model is easy to adjust; message me if you'd like a different size plug (or none at all).
