Description

PDF

This model of plastic piggy bank is being sold all over Amazon, Aliexpress, etc, etc, etc.  It comes with a very weak rubber bung.  I printed this out with PLA and has a very tight half-turn twist-lock fit by inserting it in the keyed opening of the bottom of the piggy bank and turning counterclockwise.  These piggy banks are cheap, but the problem is annoying.  You could probably also just print it out of TPU if you wanted it to be a little easier to open back up.
