I’m thinking of designs for the waterproof case, and how to make sure you can still press the buttons. I spent like an hour trying to find a proper button case, but nothing would fit the model I use. Luckily, I’ve come up with two different options that both look pretty good [in theory haven’t tested it yet]. For the first one, I would have to cut out small rectangular pieces of silicone and glue it. But the second one is just a big piece of silicone that is held together by the two halves of the case.
