AA battery pack replacement

thingiverse

Print with support! This is a battery pack replacement for a device that runs on 2 AA batteries. This printed piece is 2mm shorter than real batteries to accommodate a small screw on the the end to act as the electrical contact. Make sure you test your power supply to have the correct polarity and voltage! I have soldered the ends of the wires to the screws, and used the heat from my soldering iron to fit these back into the 3D printed plastic. If you try to screw in the screws, you'll almost certainly break the electrical connection.
