Monkey NEMA extruder motor rotation indicator

The monkey from the classic toy "Barrel of Monkeys". Just a simple resize to match the other extruder visualizers. I used a 6x3 magnet purchased from Amazon: https://www.amazon.com/gp/product/B074T9FDCK

I didn't add an indent for where to place the magnet because it might look better spinning off center. Without it, you might have to stack an extra magnet so it doesn't rubs against the motor exterior depending on magnet size.
