About this model

You get to the supermarket and realise you have no change in this cashless age to unlock the trolley! This design allows you to keep it attached to your keys and unlock a trolley and not have your keys hanging while you shop! You can even be a hero and unlock a trolley for another shopper who is there at that time in the same situation. This is a remix of a removable trolley coin slider by P_G. I really liked the design with the slider but when ever I printed it the slider would jam when sliding back or come out of the runners easily. I originally printed it in PLA and when I first used it the slider fell out but it unlocked the trolley still! But to remove it I had to squeeze it together and it snapped. So I redesigned it to add a longer back so I could add a hole to attach it to your key…
