Tight Change: A coin-dispensing card

thingiverse

Paying with cash is powerful, but one minor hassle comes in the form of change. You may be one of two people: My Dad or My Sister. * My Dad collects loose change into a jar and months or years later, he counts it and reclaims its value. * My Sister carefully collects loose change into a coin purse, but every time she makes a purchase, she spends a few seconds digging into the pouch. **No More!** With "Tight Change", everyone can hold onto their change and quickly spend it whenever needed. Revolutionary "bobby-pin" technology holds coins in place, working even with low-quality prints. I used to believe that 99¢ is the perfect amount of coins to hold, allowing you to always make change for anything you purchase. However, this comes with a problem when reusing your container: the first shopkeeper might give you exact change, but the second one might give you coins that won't fit in your container. The $4.24 design holds * 3 dollar coins * 3 quarters * 4 dimes * 1 nickel * 4 pennies Since there is redundancy, you can even make change from your existing coins: trade a dollar coin for four quarters and store a quarter in the dollar slot, or exchange three quarters for two dimes and a nickel.
