AA Battery Eliminator Power Adapter

thingiverse

This Adapter is designed to replace standard AA Batteries with a connection to a battery pack of higher capacity (but same voltage) or any external power source that can provide power for a longer time. It can be used on older cameras or other devices that don't have a separate power plug. The voltage of the external power source should match the initial battery pack voltage. On both sides (+, -), screws, nuts, and washers are used to hold the wires in place. The length of the adapter can be adjusted by increasing or decreasing the number of washers on each side (easier on “+”). Materials needed: * 2x M3 screw * 2x M3 nut * 4x washer for M3 screws To get a flatter (-) side, a flat head M3 screw can be combined with a M4 washer. There are four different versions: from A – less material to D – more material. The AA BEPA ver.A pref.stl version is preferred and should work fine in most cases. Depending on the situation, there are several modes of connecting, combining, and using this adapter (see pictures): * Adapter with two poles * One adapter for each pole * Placeholder transfer adapter To ease up printing overhangs, two thin layers are inserted on both ends. These must be cleaned out with a drill or screw before use.
