Painless360 shared this project on 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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
