Shopping Cart "Canada Loonie" Key

thingiverse

50mm long, 1.9mm thick, and Ø26.5mm at the business end. It has a Ø5mm keyring hole at the end and a nice little design on top & bottom faces and that pivoting key-action just like what they use at Walmart! I went to Walmart and couldn't find a $1 Loonie coin necessary to unlock a shopping cart. If you don't have the dollar, you need to stand in line at customer service, in amongst everyone returning their things, and eventually you can ask the lady to unlock you a cart so you can shop for free (which everyone does anyway, since you get the $1 back when you return the cart). I was shopping for heavy items including apples & oranges, 20kg of kitty litter, 20kg of water softener salt, cans of pop, and stocking up on those $1 boxes of juice. Plenty of heavy stuff that isn't easy to buy without a cart! But whereas I may not have $1 in change I do have a 3d modeler, a 3d printer, and some wood-filled filament. Here is a shopping cart key for emulating a Loonie coin for Canadian shoppers (who also happen to have a 3d printer). I also made a pattern with 5 keys (.3mf format) in case I need to replace one that's worn out or broken or I gave one away to another frustrated shopper.
