A slot for your slim wallet that holds coins.
I pretty much made this because i love the full metal slim wallets but hated carrying change in my pockets or only carrying notes. so this card rectifies that flaw. i am able to carry 6 pound coins.
various thicknesses to carry more than just coins if the need be. carry thin usb sticks, keys, sd cards.
Size is standard credit card size (with tolerance added in)
Either print with backboard or stick it to a card (like i did with my donor card in the images)
print in a snazzy colour and give the coin card a bit of life! or just print it in grey like i did... boring.
Hope you find this as useful as i do.
AfterEdit; I have just realised i took all the photos in vertical... I am so sorry please forgive.
I printed it using the settings above. Change a few settings, try something different.. go nuts.
