Trolley Key

thingiverse

This is the Australian version of the trolley key, it imitates a $2 coin and tricks the lock mechanism. It remains fully retrievable (rest assured you won't lose it to the trolley). The grip is easy to pull on, ensuring the key is retrieved regardless of circumstances. All edges and points are curved so as not to prick or discomfort you. The design measures 2.8mm thick and roughly the size of a business card, making it simple to store in a wallet or pocket. Edit: Version two (v2) features rounded edges and a more slender version of the 'coin' for easier retrieval. I have left version one in the files in case anyone wants it. Edit: In version three (v3), the writing and labeling have been removed for a more understated appearance due to popular demand in the comments section. Note: If you want a British pound version of the key, note that the British pound coin is 1.1x larger than the Australian $2 coin, so all that's needed is a small scale adjustment.
