That’s a great idea, and I’ve done that for years, especially back in the days before HA’s could be found waterproof (Aquaris) or at least splash resistant. I also keep a couple q-tips and spare battery in there when I do use the setup.
Nice. What is that box designed for? Obviously it’s too small for a phone? Do you have a model or part number for it? Or at least the dimensions? I’ve used a variety of small plastic containers, but they all seem to eventually break in my pocket. Guess I should watch where I’m going.
