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

thingiverse

UPDATE:Printed coin pick and tested today - works like a charm and somewhat better that coat hangar version - printed in PLA.Not tested yet - tab pick (the one to eject the coin) *Dummy coins printed a touch under spec on my i2, my i3 is better calibrated but is waiting on new step sticks, and my self-designed machine is still in progress. I originally designed this tool from 2.5mm diameter coat hangar wire, when I was working as a trolley collector. The token system issued by the designers:http://mrvsolutions.com/En/index.html Just was too much of a pain to use when one has to collect over 1000 trolleys a day. If you understand the internal mechanism of the lock, you can use the second tool to eject a coin if it's still present in the trolley. I'll get round to making a tutorial video on this at some stage. I have yet to print and test this design, but have included an image of an original prototype. Will post an update when I have - It's on the bed as we speak. I have also included coin dummies for Australian $1 and $2 coins. Everything you need to get practiced with these tools on a budget. If you want to remix it - I'll gladly post the cad files. ------------------------------CAUTIONS!---------------------------------------- I don't want to hear what illegal things you get up to with these as I DO NOT condone breaking of the law. Better yet - just don't do anything illegal with them. FYI modern coin acceptors on nearly all vending machines know plastic from metal. Some even have cameras and GSM modems - you have been warned!
