AA Battery Eliminator Power Adapter

thingiverse

This Adapter is intended to provide a method for replacing standard AA Batteries with a connection to a battery pack of higher capacity (but same voltage) or any other external power source that could 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/decreasing the number of washer 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 4 different versions, from A – less material too D – more material, <b>AA BEPA ver.A pref.stl</b> – preferred, should work fine in most cases. Depending on each particular 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 using.
