In this project we’re going to 3D print a battery tester using dual extrusion and conductive filament. With an LED you can use this to test coin cell batteries. The outter shell is PLA while the traces and pads are printed in conductive filament. It’s embed within the part and prints all in one piece!
When you hold a battery in between the pads, it conducts electricity!
This highly conductive filament is from the fine folks over at Protoplant, makers of Proto Pasta.
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!
