This is a remix of the Money Cat created by bs3
UPDATE 11/8/18: I remade the bank and added a plug in the bottom so you don't have to break the bank to open it. Also the walls are thinner (but still strong) and uses much less plastic to print. If the plug is too tight, you can print it at 99% - that will depend on the tolerance of your 3D printer. (More pictures added also)
My daughter really loved the regular design but kept shoving dollars into the bottom and many didn't fit, so she had a fit (she is 3 years old)
I decided to take the money cat and make it bigger, seal the bottom and add a slit on the back of the head to add dollars.
My daughter is really happy now ;-)
