The holiday hackery continues!

This is a serious bank, for people who are serious about saving money. You can put money in, but can't get it out without smashing the bank.

To make it easily smashable, and to make it easy to print replacements, it's very thin.

I'm printing them for my kids for their holiday money and homework.

It's customizable:

• Size. 50mm is small, 100mm is huge. (8x the volume)
• Money slot: alter the size to support your preferred currency
• Shape: diamond or rounded.
• All sorts of tweakable settings
