More or less out of boredom, I designed a small organizer “box” for two USB Wi-Fi dongles, since my work PC doesn’t have Bluetooth (for my headphones). The symbol I chose is just a completely random logo that came to mind at that moment. I can also make it without any logo, or you can add your own if you prefer :) About 5 mm before it fully closes, there’s a click-lock mechanism, and the box snaps shut nicely.
