First project I've made for Instructables. It's an elegant Mario Coin Brick Bank.
The measurement for this bank is 7" x 7" x 7". I made it 7 7 7 because the number 7 7 7 from the slot machines. If you get those numbers from the slot machines, you'd get a whole lot of coins. Well in this case, you do also. It's just that you have to fill it up with a bunch of coins and then pull the stopper from the bottom and the coins will spill out.
Also, this is made from particle board. So if you decide to fill it up to the max and decide to hit it with a sledgehammer, you'd also get a lot of coins. Enjoy.
