Shopping Cart Key / Einkaufswagenschlüssel

A Shopping Cart Key that does not need to remain inside of the cart. Just angle it slightly and pull it out after unlocking.  Designed for german carts that take 1€ coins, so it should work in the whole euro zone. Maybe it will work for other currencies as well, i'd love to hear about it if it does.  

There are some similar models like this out there, but i found that most of them slide in badly or are a hassle to pull out again. This one, at least in the Lidl carts i tried so far, slides in perfectly and easy without any force and can be pulled out again by very slightly angling it.

Printing Instructions

• use a sturdy low friction material like PETG or Nylon.
  • PLA might work, but i'm not recommending it
• use small layer heights like 0.1mm for a smoother finish
• align the seams at the backside where the keyring hole is
