150 Euro Saver

This coin saver stacks different amounts of 2€, 1€, 50ct, 20ct and 10ct Coins, with the goal to save 150 € when all coin registers are filled to the top.

5ct, 2ct and 1ct coins cannot be stacked.
The top part is optional, but it gives a nicer look.
No glue needed.
The coins do not sit in there tightly, so they'll eventually fall out if you shake this thing.
I have never actually filled this thing entirely, but I hope that my calculations for the coin-stack heights were correct.
