This is a VERY beta design. I was inspired by a video on YouTube of a guy making a battery out of an aluminum can, copper wire, and salt water. http://www.youtube.com/watch?v=yA6Jde77UNc As a kid I had made similar batteries using zinc, copper, and salt water.
For this you will need:
- Copper wire
- A small sheet of zinc - although you could modify the design and make it work with a galvanized nail (aka zinc coated nail)
- Bits of wire
- Salt water
- Some acetone or ABS glue if you want to seal it
- A MakerBot that can print water tight objects
My 'bot is out of commission for a few days, so I won't get a chance to try this out for a little while. If you do try, please let me know how the design works for you.

Instructions
- Print both parts
- Bend a long piece of copper wire into a small hook at one end and then a thick coil, leaving a long unbent piece at the end
- Put the hook through the loop in "A" (This is represented by the blue squiggles)
- Punch a small hole into the sheet of zinc and either bend a piece of wire around it or solder a piece of wire to it (This is represented by the green stuff, with the wire being the purple stuff)
- Bend a thin sheet of zinc into a cylinder and place it into the groove in "B"
- Put the long unbent end of the copper wire through the hole in the lid
- Put the wire from the zinc sheet through the hole in the lid
- Fill with salt water mixture
Close the lid on top (and seal with acetone or ABS glue if you like)
Edit:
A drop of acetone or ABS glue should create a watertight seal around the holes for the anode leads.
