3 AA Battery Box
thingiverse
Create a battery box for three AA batteries to power a 3.3V microprocessor project. The box features #6 nuts and holes for 1/4" #6 bolts, but bolt usage is optional. After inserting batteries multiple times, the nuts will fit snugly in place. Optionally use wire or copper tape to connect middle battery to outer ones; tuck tape into nut hole before securing with nuts. Insert a stripped wire into backside hole and press nuts tight with pliers. For added stress relief, apply glue to wire hole if desired. Finally, insert 3 AA batteries as shown in the picture and enjoy your functional project.
