3x 18650 12v Battery

thingiverse

A case to hold 3x 18650 battery cells in series making a 12v battery pack. i used it to make a torch, made it rounded and not triangle to have a better feel in hand. Instructions Ive used small screws with springs around them to make the terminals. Adding copper wire underneath when screwing them in to make a connection. the top cap has one hole slightly larger than the rest for the wire to be placed in and a screw holding it in place making your first + or - the other wire passes through the body from the base. the other terminals get joined in order for a series connection. For more clarity please refer to pictures or just ask. the base and cap are held one with a single larger screw though the center. Printing. the base and cap should be printed with thicker walls ( at least 3 ). the body can be printed how you think best
