This is a multi-material print that uses a conductive filament and an insulating filament. All you need is an Adafruit circuit playground and 8 screws. I have also included some basic code to help you get started (adapted from Carter Nelson's code, link below).

It won't let me upload the .ino file so here is a copy of my code:
