This skull is designed to house two 1.44" TFT screens from Adafruit that display eyes from the Uncanny Eyes project. An ultrasonic distance sensor triggers the eyes to change. Put it on a grapevine wreath and you'll have a haunted wreath for your door.
In addition to PLA (or ABS if this will be in the sun), you will need an HC-SR04 distance sensor, a Teensy 4.1, two 1k ohm resistors, and two 1.44" TFT screens.
There's only one piece to print, but it's a big one, and it's going to need supports. I have it oriented in a way that will require maximum supports, but it keeps the face of the project looking cleanest. Re-orienting to be face down will reduce the amount of supports needed but could result in issues showing up on the face from the removal of the support material. I found Cura's tree supports to be great on this project.
