My model is the piano buddy. The piano buddy is articulated not only the legs are but  the keys are too. The piano buddy can sit wherever, like your desk printer or a piano. The piano buddy is a faster print witch uses minimal filament. The piano buddy is also durable. To get the file to print this buddy you need to you use the file I have and transfer it to your printer. When the print is finished the keys will be all separated so you will need to feed wire through the holes on the back of the keys to keep them together. Hope you choose to print this buddy.
