Hi , this is a simple holder for a Joule thief circuit and an AA battery.
If you don't know what a Joule thief is ,search for bigclivedotcom on youtube. It's where I copied the circuit from. There are many other videos that explain it as well though.
Here's the Wiki definition
A joule thief is a minimalist Armstrong self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads.
It allows you to run a 3v LED from a single dying 1.5v AA cell. The one in the photo has been running for 37 hours on a dead battery out of a kitchen clock. (starting voltage 0.79v)
The holder is printed at 0.3 with 0 to 20% infill
