Shopping trolley / Cart lock pick - with dummy Australian coins.

UPDATE: Coin Pick and Toolset Successfully Printed - Outperforms Coat Hangar Version. Works like a charm, prints in PLA with precision. Tab pick to eject coin has not been tested yet. Dummy coins printed undersize on my i2, but my calibrated i3 printer is waiting for new step sticks. Meanwhile, my custom-built machine is still under development. Initially, I created this tool using 2.5mm coat hangar wire when working as a trolley collector. The token system developed by mrvsolutions.com was cumbersome and difficult to use when handling over 1000 trolleys daily. Understanding the lock's internal mechanism enables coin ejection using the second tool even after collection. A tutorial video is in the works for these practical tools. Printed designs, including a prototype image, will be shared upon successful testing - currently printing as we speak. Additional materials include Australian $1 and $2 coin dummy prints. All necessary resources are included for practice on a budget, with CAD files available for remixing purposes. CAUTIONS! Use discretion with these tools - I disapprove of any activities that disregard the law. Best approach is to avoid such uses entirely. Modern vending machines equipped with advanced security features, including camera and GSM modem capabilities, detect both plastic and metal inserts - a word of caution is in order!
