The 'Glow' circuit assembly

Assemble a simple, pre-made circuit with light that you can incorporate into your 3D designs.

1. Introduction

In this tutorial, you'll learn how to build light up 3D designs using the Glow Circuit Assembly, which combines a light emitting diode (LED) and a coin cell battery. It's a simple way to incorporate a bit of light into your Tinkercad designs. We provide the 3D model for the circuit holder and cutout, and you incorporate it into infinite glowing fun!

You'll need 3D printing tools, a pair of wire cutters, and two electronic components:

  • An LED (shown is 10mm). It is an electronic component that emits light when activated.
  • A 3V Coin Cell Battery (CR2032)

IMPORTANT: Coin cell batteries can cause serious injury if swallowed. Keep coin cell batteries out of reach of small children!
