LED Mason Jar Lanterns

In this easy 3D printing project, we’ll build glowing mason jar lanterns containing a simple LED and battery circuit. Download my file or build your own custom lid using the Glow Circuit Assembly in Tinkercad, which is designed to hold the battery and LED together perfectly. I’ll show you four different ways to style your lanterns using materials you probably already have around.

If I hadn’t gone to Maker Faire, all the GIFs for the project would be like this one:

more GIFs after the jump.
