Happy Shopping Cart Coin Holder

Happy Shopping Cart Coin Holder

For most shopping carts at the supermarket you need a coin to unlock the shopping cart.
There are a lot of replacement coins with holders that can be attached to your keyring. So here is another one, happy to hold your coin until you need it.

This coin holder is designed for a coin of the size of an 1 Euro coin.
Cheap: (about 10Ct for the PLA compared to the 1 Euro coin. So it is about 10 for the price of one. ;-))
Quickly available: the holder with the coin can be printed in about half an hour.
Supportless print: can be printed without support material.
Keyring compatible: can be attached to your keyring (the two holes in the holder are made for this...)
Smiles happily when holding your coin.
Carabiner compatible coin: if you just print the coin with the hole in it, you can attach it to a small carabiner instead of the holder and keep more than one coin, too.
Perfect for testing new filament. Afterwards you can use it as little 'giveaway', so you don't waste the filament for the testprint.

Have fun!
