I always seemed to have a pile of coins at home or in my pocket.
This coin holder ensures that I have just enough coins to provide exact change for any transaction. I throw a few of these filled coin-holders in my pocket before any shopping outing. Now my coin pile is much lower.
Print so that large opening is at top to respect the 45deg overhang rule (will require a rotate).
I use this method to derive the coin combination from a pile of coins:
1) Start from the lowest denomination. Select the maximum amount of coins that is still less than the the next larger coin.
2) Do the same with each higher denomination.
OpenSCAD file is here so you can customize for your own currency.
