Makita 9.6 Battery Case

thingiverse

A 12-volt source-powered Makita power tool battery case can be created using the provided top and bottom files of a 9.6-volt Makita battery. Both parts are printable with most 3D printers, measuring less than 4" or 100mm tall. A 12V cigarette lighter adapter powers the drills effectively. To make contacts from metal sheeting, heat aluminum strips to 1/4" by 4", melt the ABS to insert tabs, and insulate with shrink wrap. Drill modification involves removing excess plastic from the handle and wire exit site. Create a hole in the battery case for wire passage, secure wires to metal strips inside the top part, and cover connections with shrink wrap, attaching positive wire to the marked side. Assemble and secure with a screw if needed; it provides great power output.
