CR2032 Button Cell Holder

thingiverse

This is my design for a simple easy to print CR2032 button cell (or any 20 x 3mm cells). Using a paper clip to make the contacts and a spare piece of 1.75mm for the 'off' button it's simple to put together. The sides are designed to hold the battery against both the contacts and the plunger can be used to push the battery away from the lower contact acting as a crude 'off' switch. Simply clip a 10mm length of filament and warm the end and then mushroom it against a hard surface to create the blunt end to push on. I've made this for use in a small project where I want a couple of LEDs lit but I need the ability to turn them on and off easily.
