Here is the B9 Environmental Control Robot from Irwin Allen's Lost In Space TV series, made into a fun coin bank, easily printable on your 3D printer.
B9 was designed by Robert Kinoshita, who also helped create Robby the Robot for the 1956 sci-fi classic Forbidden Planet.
Use this as a coin bank or, if you prefer, insert coloured LED lights and invite B9 to your next dance party.
Print without support using transparent filament and glue the two halves together.
