11.1 Volt Battery pack

thingiverse

This is a custom battery box I created to fit 3.7 Volt batteries, featuring a hinged cover held in place by 2-56 machine screws. The small squares indicate where to drill for the screws. To make the contacts, I used copper sheet and scissors to cut out tabs, then folded them into a two-layer design that fits snugly into a slot with one tab protruding through a recess to make contact with the batteries.
