Waterproof case reusing growler lids

thingiverse

I live in an area where growler lids aren't accepted for recycling. One evening, while sipping my beer and fiddling with the lid, I started thinking about some way to reuse it. The first thing that came to mind was this waterproof case, which is essentially a simple tube with growler threads on each end. I've made both 50mm and 100mm versions so far, but if you need one in a different length, just let me know, and I'll create it for you.
