ALDI Australia trolley key (removable)

thingiverse

This part is a keyring which acts as a key for the trolleys at Australian ALDI stores, and other trolleys which accept an Australian $2 coin. The key can be inserted straight in to unlock a trolley, but the key can then be removed diagonally before returning the trolley. This is so your car keys can remain safely in your pocket, not so you can be lazy and make a mess of the carpark. Please be considerate. The STL contains four keys, since they're tiny, cheap and fast to print. Share them with your family or keep one on every keychain you have.
