I love Halloween! Making costumes for my kids is a lot of fun. Every year they pick a character or theme and I ask, “How much of it can we 3D print and do you want to add LEDs?” This year was the electronic music producer and DJ, Marshmello.

This Marshmello Helmet uses a concrete form tube as the base with 3D printed grid components framed around the outside of the form tube. LEDs are used in each square and the entire helmet is wrapped in a flexible translucent PE sheet. The lighting pattern is controlled by an Arduino Pro Mini.
This project requires the following items that are not covered in detail in the project:
- Arduino
- Writing code
- Programming Arduino
- Uploading sketches
- Soldering
- 3D Printing”
