Saw that someone had modified Banzai Bill to hold games. In this house we play animal crossing far more often so something had to be done.
The hat is removable/optional and can be glued or left posable...
Arms are press-fit tabs and move (rotate) once installed. However, once in, they don't come out. Holds a baker's dozen game cartridges.
The game holder is an insert that you can leave out if you have other ideas.
The arms and hat were the only parts that needed support material. For the hat, just a column to support the top of the arc/dome.
