Apple Keyboard battery knob

thingiverse

This is a trivial solution to a trivial problem. I don't like the way that the battery cover on Apple's keyboard and trackpad screw on/off. It's supposed to be easy. No tools required, just use a coin. I suppose I could just leave a quarter sitting under my keyboard, but that wouldn't be any fun. Instead I made this little knob to do the job. I actually glued the knob to the screw caps it's always there.
