A remix of the remix from hijinksensue of his Smart Wallet.I made it just a little bit thicker so the money and the coins fit better, also I have changed the bottom lock of the lid, so it doesn't interferes with the coins, and optimiced the size of the rail, so it takes less space.
There are 2 types of cage and lid, the only diference is the size of the lock, choose the one you prefer.
The lid files with "_LT" at the name, have less tolerance at the lock. Print if your wallet doesn't stay closed.
