Pokemon themed prints are all the rage right now. Speakboylese shared this project on Thingiverse!

A “piggy” bank version of the low-poly Bulbasaur. I hollowed out FLOWALISTIK’s model and added a coin slot on top and a hole on the bottom for dumping the coins out. The second file is for a flat plug to fit in the hole. It should snap in and pry out easily, but there’s a small slot on the edge of the opening where you can insert something to help pry it out if it gets stuck.
