This is my second generation halloween crow, now with an animated head and blinking eyes. It is in 5 pieces that are designed to be sliced and printed in "vase mode". The crow is about 18" (45cm) long when assembled. The largest section that you will need to print is about 7.25" (19cm) tall and about 5" (13cm) wide. I printed this in black PLA and used hot glue to attach the feet. There is a short section that attaches to the tail so that it can be press-fit to the body. This allows access to the electronics/battery compartment. The controller is an Arduino Uno. The eye holes were created with a drill and the LEDs are press fitted.
The arduino code to run this is attached as CrowServo.ino
I just finished this project today (Oct 31st 2016). I'll be adding more details later.
