Bottle Cap Keyboard
thingiverse
This is a blueprint for a "Bottle Cap Keyboard", a compact replica of The President's Key. Although I created this for an Arduino Pro Micro case, it's actually a fully functional single-keyboard that can be used as a hotkey-board. Grab any favorite PCO1881 standard bottle cap (most soft drink bottles comply). I programmed it with Cmd+Q(mac) / Alt+F4(pc) for quitting applications but you can change it to any key command.
