Overview

In this project we're making a 3D printed case for the hallowing! We added spikes to design, making it easy to attach to pumpkins! This last minute halloween prop is easy to 3D print and stick onto almost any soft surface!

 

The Adafruit hallowing is a full tricked-out Feather M0 Express with sensors and a built in screen.

 

Our 3d printed case features spikes! These decorative and functional spikes allows you to attach to pumpkins! This is the cleanest way to decorate your pumpkin this year.
