Description
This thing unlocks a shopping cart.
After unlocking you can remove it from you shopping cart ant put it back into your pocket.
You can also attach it to your keychain.
Tested in Germany, should work across Europe.
Update1: I've added a mix between my solution and an existing coin solution. To print this remix you will need Prusa Slicer (The Goose.3mf)
Update2: I've added a minimal version that is closer to the coin size (unlocker-minimal.stl)
Update3: I've added a longer variant (5 mm longer) of minimal version (unlocker-minimal-longer.stl)
