Key Protector Spiked Ball

thingiverse

Where I work, our master key seems to vanish inexplicably often. To prevent that from happening, I designed these spikes to be extremely pointed due to their precise positioning on the metal surface. As a result, carrying this in your pocket won't be comfortable at all - it will make a lasting impression, ensuring the key gets returned promptly. Exercise caution when printing this design as it could potentially cause harm if not handled carefully. This is no toy; its sole purpose is to serve as a reminder for people to return the master key to its designated spot after use.
