My take on the shopping cart coins.

These euro-coin replicas — 1€, 2€, and 0.5€ — are precisely modelled to match the real coins’ diameter and thickness, ensuring they fit perfectly into European shopping carts.

Each coin features a small tab for easy pushing or pulling, plus a hole so you can attach it to your keyring and always have it on hand.

In my experience, the first few uses might be a bit awkward to slide in the mechanism, but it works. I have also used the 0.50€ coin and I was able to pull it out without "unlocking" the machine. Please be responsible when using these.

Printing Recommendations Material: PLA is ideal for rigidity, but any material works as long as it doesn’t flex too much.

Infill: I've printed these as low as 10% and it has worked, but feel free to use as much as you desire
