Trolley (shopping chart) chips

thingiverse

I'd been frustrated by being completely out of cash, not to mention losing my stored-value card that was in the car for easy checkout on shopping charts. So I came up with a plan and printed them myself in ABS, which worked like a charm - now the one with a clip is securely attached to my keychain since it's for our primary supermarket where we go every week. I designed it using Fusion360 and truthfully, it was possibly the easiest piece I've ever created.
