Key Separator/Divider - Tactilely find F-Keys on Apple Keyboard

thingiverse

The bump key helps you identify each function key on a standard Apple wired keyboard without needing to look down, offering tactile feedback with every keystroke. This device fits snugly between the function keys on your Apple keyboard and is specifically designed for use with that particular brand. It may work just as well on other keyboards too, although I wouldn't count on it for sure. I created this because new Mac keyboards no longer have individual sets of four F-keys like earlier models did, causing me frustration from the very beginning (it's been just eight hours so far).
