Start a new tradition and design your own Tree Topper. Celebrate this holiday with DIY electronics from Adafruit. Our tutorial will show you how to use Autodesk's 123D Design software and a 3D Printer to create a custom tree topper.

This is a great "Learn to 3D model & print" project as the shape is fairly simple, snaps together and can be customized.
This guide was written for the 'original' Gemma board, but can be done with either the original or M0 Gemma. We recommend the Gemma M0 as it is easier to use and is more compatible with modern computers!
