AA Fake Battery Housing

thingiverse

Housing that can be placed instead of an AA battery in a device to connect it to an external source. You will typically need two: one for + and other for - pole of the device. (It doesn't work for devices with only one AA battery). Simply print out and add a standard M4 screw with a nut to serve as a contact - the nut can be used in the inner side to secure the wire, but of course, any other way of connecting a wire to the screw can be used, and the screw itself may be a lot shorter than one visible in the photo (in the photo it's the M4x30). It is designed to be printed without support, as long as the side with the hole faces downward. The result is a bit brittle if squeezed in the middle, but otherwise it does its job fine - the most strain such a battery withstands in a device is anyway longitudinal, not lateral. Prints in the photo done on Ender 3 Pro.
