Printable Battery

This is a preliminary design inspired by a YouTube video showcasing battery creation from an aluminum can, copper wire, and saltwater. As a kid, I had made similar batteries using zinc, copper, and saltwater. To replicate this design, you will need copper wire, a small sheet of zinc (or a galvanized nail), bits of wire, saltwater, and optionally, acetone or ABS glue for sealing. Utilize your MakerBot to print watertight objects. As my 'bot is temporarily out of order, I won't be trying this soon; please share your experience if you do. To assemble, print both parts, create a copper wire hook and coil, attach it to the zinc piece, bend a thin zinc sheet into a cylinder for part B, pass the copper wire through holes, fill with saltwater, and seal (if desired). A drop of acetone or ABS glue can provide a watertight seal around the anode leads.
