Flexible key cover - Flex key cover

Several months ago, I introduced a new habit of taking regular walks. The constant jingling of keys in my pocket had become increasingly frustrating, prompting me to explore alternative solutions. One day, I had an epiphany - why not leave just one key behind? But even that single key could be an annoyance when carried in my pocket. To resolve this issue, I decided to design a custom sleeve using flex filament that would hold and protect the key while also making it easier to carry around.
