Economy Book

Is it annoying when you have no idea how much you have collected to your piggy bank? Then you robber it to "calculate" and waste it something you dont need.

This bank is much better organized. The idea is to collect all loose 2€ coins by your decision to do so. The side of the "book" estimates your saldo. The full bank will hold 1680€ !!

I said "book" because this bank looks like book enough to hide in your bookself. Just print a label which doesnt collect too much interest.

I made the bank robbering a bit difficult in purpose. The funds are quite much sealed until you smash the bank (which you hesitate to do). Specially if you push in the last coint a bit forcibly, it will stuck in all the pile.

Please let me know if You desire other currencies!

Update: Canadian 2$ version added. I made it quick way, scaling x/y to coin diameter with 1mm gap and height matching to 1.8mm coin thickness. Therefore the filament fixing holes are slightly widened. should be fixable with glue.

You will print upper and lower parts separately and glue them together aiming and locking the halves with cut sticks of 1.75mm filament. Dont mess with too much glue to make sure the coins slides in freely.

The bank will weight 7kg or more but I think low infill is still good to go.

Verify Your setting after 10mm or so by dropping in 2€. It should fit easy.

If You cover the front with paper print anyway, You could consider using transparent filament.
