Battery converter.
This is to convert a 3x AAA battery compartment to a 1x18650 Li-ion.
Device seems to burn through the AAA batteries really fast, so this allows device to run off a 18650 Li-ion battery and so battery life greatly improved.
it's a two part print. Stick them together and add your connectors.
