Update - It is not necessary for you to print the plug separate. It was requested after one broke.
Update 2 - It was requested that I also make the bank available without the plug in it. I've also gotten a lot of questions about the inside top, so I've added a picture of what it looks like.
Bank designed to be printed in one single piece with NO supports! This also includes a print in place plug to make everyone's life a little easier. Be sure to print with 2 perimeter walls.
